  • Page 16: Vlans And Routing

    VLANs to route IP packets and bridge nonroutable traffic in specifically assigned VLANs. Virtual routing between VLANs The Avaya Ethernet Routing Switch 8800/8600 supports wire-speed IP routing between VLANs. As shown in the following figure, although VLAN 1 and VLAN 2 are on the same switch, for traffic to flow from VLAN 1 to VLAN 2, the traffic must be routed.

  • Page 17: Brouter Ports

    VLAN. Brouter ports The Ethernet Routing Switch 8800/8600 supports brouter ports. A brouter port is a single-port VLAN that can route IP packets and bridge all nonroutable traffic. The difference between a brouter port and a standard IP protocol-based VLAN configured to perform routing is that the routing interface of the brouter port is not subject to the spanning tree state of the port.

    IP routing features and considerations The Ethernet Routing Switch 8800/8600 has features and capabilities that you can use to maximize routing efficiency. This section contains information that you can use to help you configure IP routing.

  • Page 21: Alternative Routes And Route Preferences

    Routers can learn several routes to a destination network through several protocols. In the Avaya Ethernet Routing Switch 8800/8600 software, if the alternative route feature is enabled, the switch stores the alternative routes sorted in order of network mask, cost, and route preference.

  • Page 22: Route Policies

    Route policies When the Ethernet Routing Switch 8800/8600 routes IP traffic, a number of route policies (filters) can be applied to manage, accept, redistribute, and announce policies for unicast routing table information. The filtering process relies on the IP prefix lists in the common routing table manager infrastructure.
  • Page 23 RIP instead of from OSPF. The network prefix is a commonly used match criterion for accept policies and ingress filters. Use RIP accept policies on the Ethernet Routing Switch 8800/8600 to selectively accept routes from RIP updates. If policies are not defined, the default behavior is applied, which adds all learned routes to the route table.
  • Page 24 3. Filter stage 3 is the announce policy or out filter. This filter is applied to outgoing routing protocol updates within a protocol domain. The following figure shows the logical operations that occur during the route-filtering process in the Ethernet Routing Switch 8800/8600. Configuration — OSPF and RIP June 2011...
  • Page 25 IP routing features and considerations Figure 8: Route filtering logic For information about configuring policies, see Avaya Ethernet Routing Switch 8800/8600 Configuration — IP Routing, NN46205-523. Configuration — OSPF and RIP June 2011...

  • Page 26: Port Routing Control

    Configure RPC as required for each IP interface. When enabled, the Ethernet Routing Switch 8800/8600 checks all routing packets that enter the interface. RPC ensures that the source address and source interface appear in the routing table and that the address matches the interface on which the packet was received.
  • Page 27 IP routing features and considerations Figure 9: Reverse path checking network configuration Consider the following parameters: • A router (Ethernet Routing Switch 8800/8600) connects a server (32.57.5.10) to a client (192.32.45.10). • The router has RPC enabled. • The router has the following entries in its routing table.

  • Page 28: Multihoming

    Multihoming Using the multihoming feature, the Ethernet Routing Switch 8800/8600 can support clients or servers that have multiple IP addresses associated with a single Media Access Control (MAC) address. Multihomed hosts can be connected to port-based, policy-based, and IP subnet- based VLANs.
  • Page 29 Circuitless IP Figure 10: Routers with IBGP connections CLIP 1 and CLIP 2 represent the virtual CLIP addresses that are configured between R1 and R2. These virtual interfaces are not associated with the physical link or hardware interface. The IBGP session can continue as long as a path exists between R1 and R2. An IGP (such as OSPF) is used to route addresses corresponding to the CLIP addresses.
  • Page 30 Routing fundamentals Configuration — OSPF and RIP June 2011...

  • Page 31: Chapter 4: Ospf And Rip Fundamentals

    In routed environments, routers communicate with one another to track available routes. Routers can dynamically learn about available routes using the Routing Information Protocol (RIP). The Avaya Ethernet Routing Switch 8800/8600 software implements standard RIP to exchange Transmission Control Protocol (TCP)/IP route information with other routers.

  • Page 32: Rip And Route Redistribution

    RIP Version 1 advertises default class addresses without subnet masking. RIP Version 2 advertises class addresses explicitly, based on the subnet mask. The Ethernet Routing Switch 8800/8600 supports RIPv2, which advertises routing table updates using multicast instead of broadcasting. RIPv2 supports variable length subnet masks (VLSM) and triggered router updates.

  • Page 35: Dijkstras Algorithm

    Open Shortest Path First In large networks, OSPF offers the following benefits: • Fast convergence When network topology changes, OSPF recalculates routes quickly. • Minimal routing protocol traffic Unlike distance vector routing protocols, such as RIP, OSPF generates a minimum of routing protocol traffic.

  • Page 36: Autonomous System And Areas

    LSAs. Note: ERS 8800/8600 could take a minimum of about 10 seconds to populate an OSPF learned route into the Route Table Manager as it does not rebuild its router LSAs immediately when the neighbor router changes to FULL state.
  • Page 37 Open Shortest Path First A 32-bit Area ID, expressed in IP address format (x.x.x.x), identifies areas. Area 0 is known as the backbone area and distributes routing information to all other areas. If multiple areas are used, they must all be attached to the backbone through an Area Border Router (ABR), which connects area 0.0.0.0 to the nonbackbone areas.

  • Page 38: Stub Area

    When the NSSA N/P bit is set (is a 1), the ABR exports the external route. This is the default setting for the Ethernet Routing Switch 8800/8600. When the NSSA N/P bit is not set (is a 0), the ABR drops the external route. You can create a route policy on the Ethernet Routing Switch 8800/8600 to manipulate the N/P bit.
  • Page 39 Open Shortest Path First Figure 12: Multiarea configuration example For this network example, the Ethernet Routing Switch 8800/8600 devices R1 through R5 are configured as follows: • R1 is an OSPF ASBR that is associated with OSPF Area 0 and OSPF Area 3. R1 is configured to distribute a default route for Internet traffic.

  • Page 40: Ospf Neighbors

    OSPF and RIP fundamentals • The interface priority on R5 is 0; therefore, R5 cannot become a designated router (DR). • Configure the OSPF router priority so that R1 becomes the DR (priority 100) and R2 becomes the backup designated router (BDR) with a priority value (priority 50). Use stub or NSSA areas to reduce the LSDB size by excluding external LSAs.

  • Page 41: Router Types

    Open Shortest Path First All routers connected by a point-to-point network or a virtual link always form an adjacency. All routers on a broadcast or NBMA network form an adjacency with the DR and the BDR. In an NBMA network, before a DR is elected, the router sends Hello packets only to those neighbors eligible to become a DR.

  • Page 42: Ospf Interfaces

    An OSPF interface, or link, is configured on an IP interface. In the Ethernet Routing Switch 8800/8600, an IP interface can be either a single link (brouter port) or a logical interface configured on a VLAN (multiple ports). The state information associated with the interface is obtained from the underlying lower level protocols and the routing protocol itself.
  • Page 43 Open Shortest Path First Network interface type Description typically used on an access network or on an interface that is used for BGP peering. Using passive interfaces limits the amount of CPU cycles required to perform the OSPF routing algorithm. Broadcast interfaces Broadcast interfaces support many attached routers and can address a single physical message to all attached broadcast routers (sent to AllSPFRouters and AllDRouters).
  • Page 44 OSPF and RIP fundamentals Figure 13: NBMA subnet NBMA interface operations and parameters OSPF treats an NBMA network much like it treats a broadcast network. Because many routers are attached to the network, a DR is elected to generate the network link-state advertisements.
  • Page 45 Open Shortest Path First any two eligible routers always exchange Hello packets, which is necessary for the correct DR election. You can minimize the number of Hello packets sent by minimizing the number of eligible routers on a nonbroadcast network. When the DR is elected, it sends Hello packets to all manually configured neighbors to synchronize their link-state databases, establish itself as the DR, and identify the BDR.
  • Page 46 OSPF and RIP fundamentals Figure 14: NBMA subnet configuration example Because R1 and R2 have a router priority of 0, they are not eligible to become the DR. Also, R1 and R2 do not require configuration of a neighbors list; neighbors are discovered dynamically through the Hello Protocol.

    Open Shortest Path First 5. R3 and R4 each form three adjacencies (one with each router on the NBMA subnet). 6. R1 and R2 each form two adjacencies (one with the DR and one with the BDR). Passive interfaces Use a passive interface to enable an interface to advertise into an OSPF domain while limiting its adjacencies.

  • Page 55: Ospf Host Route Advertisements And Nonbackbone Areas

    Border Gateway Protocol OSPF host route advertisements and nonbackbone areas The Ethernet Routing Switch 8800/8600 does not associate a host route with a specific area. Therefore, when a host route is created in a nonbackbone area, it is not advertised through nonbackbone (nonOSPF core) areas.
