  • Page 19: Vlan Concepts

    Managed Switches VLAN Concepts Adding virtual LAN (VLAN) support to a Layer 2 switch offers some of the benefits of both bridging and routing. Like a bridge, a VLAN switch forwards traffic based on the Layer 2 header, which is fast. Like a router, it partitions the network into logical segments, which provides better administration, security, and management of multicast traffic.

    Managed Switches Port Routing Concepts The first networks were small enough for the end stations to communicate directly. As networks grew, Layer 2 bridging was used to segregate traffic, a technology that worked well for unicast traffic, but had problems coping with large quantities of multicast packets. The next major development was routing, where packets were examined and redirected at Layer 3.

It is characterized as an interior gateway protocol, and is typically used in small to medium-sized networks. A router running RIP sends the contents of its routing table to each of its adjacent routers every 30 seconds.

    PBR. However, this feature is not supported. Starting with Software Version 10.2, the NETGEAR switch supports the route-map infrastructure for BGP. Match parameters defined in this chapter for policy-based routing operate in isolation with BGP.

  • Page 147: Pbr Processing Logic

    • Destination IP address • Priority (802.1P priority) NETGEAR’s policy-based routing feature overrides routing decisions taken by the switch and makes the packet follow different actions specified in the following order to define forwarding criteria: • List of next hop IP addresses. The IP address can specify the adjacent next hop router in the path toward the destination to which the packets should be forwarded.

  • Page 148: Pbr Configurations

    Managed Switches The route map with a deny statement uses the following logic: • The incoming packet is matched against the criteria in the match term specified in the route map. This match command can refer to an IP/MAC access list. An ACL that is used in the match term itself has one or more permit or deny rules.

  • Page 149: Pbr Example

    Managed Switches The same phenomenon applies to ACLs specified in the match clause of PBR. That is, if a PBR route map is applied on a VLAN interface, any packet coming with a corresponding VLAN ID on any port is matched against PBR rules corresponding to the match ACL clause and the corresponding set actions are taken into effect.

    Managed Switches Untrusted Ports • No incoming packet priority designation is trusted; therefore, the default priority value for the port is used. • All ingress packets from untrusted ports, where the packet is classified by an ACL or a DiffServ policy, are directed to specific CoS queues on the appropriate egress port. That specific CoS queue is determined by either the default priority of the port or a DiffServ or ACL-assigned queue attribute.

IGMP snooping can be enabled to create a multicast group to direct that traffic only to those users that require it.

    Managed Switches Multicast Listener Discovery Concepts Multicast Listener Discovery (MLD) protocol enables IPv6 routers to discover multicast listeners, the nodes that are configured to receive multicast data packets, on its directly attached interfaces. The protocol specifically discovers which multicast addresses are of interest to its neighboring nodes and provides this information to the active multicast routing protocol that determines the flow of multicast data packets.
