Ospf Timers And Authentication; Rip Configuration Example - Extreme Networks ExtremeWare XOS Guide Manual

The cost metric is inserted for all Border Gateway Protocol (BGP), RIP, static, and direct routes injected
into OSPF. If the cost metric is set to 0, the cost is inserted from the route. For example, in the case of
BGP export, the cost equals the multiple exit discriminator (MED) or the path length. The tag value is
used only by special routing applications. Use 0 if you do not have specific requirements for using a
tag. (The tag value in this instance has no relationship with IEEE 802.1Q VLAN tagging.)
The same cost, type, and tag values can be inserted for all the export routes, or policies can be used for
selective insertion. When a policy is associated with the export command, the policy is applied on every
exported route. The exported routes can also be filtered using policies.
Verify the configuration using the command:
show ospf
Redistributing Routes into RIP
Enable or disable the exporting of static, direct, BGP-learned, and OSPF-learned routes into the RIP
domain using the following commands:
enable rip export [bgp | direct | e-bgp | i-bgp | ospf | ospf-extern1 | ospf-extern2 |
ospf-inter | ospf-intra | static] [cost <number> {tag <number>} | policy <policy-
name>]
disable rip export [bgp | direct | e-bgp | i-bgp | ospf | ospf-extern1 | ospf-extern2
| ospf-inter | ospf-intra | static]
These commands enable or disable the exporting of static, direct, and OSPF-learned routes into the RIP
domain. You can choose which types of OSPF routes are injected, or you can simply choose
will inject all learned OSPF routes regardless of type. The default setting is disabled.

OSPF Timers and Authentication

Configuring OSPF timers and authentication on a per area basis is a shortcut to applying the timers and
authentication to each VLAN in the area at the time of configuration. If you add more VLANs to the
area, you must configure the timers and authentication for the new VLANs explicitly. Use the
command:
configure ospf vlan [<vlan-name> | all] timer <retransmit-interval> <transit-delay>
<hello-interval> <dead-interval> {<wait-timer-interval>}

RIP Configuration Example

Figure 61 illustrates a BlackDiamond switch that has three VLANs defined as follows:
Finance
●
Protocol-sensitive VLAN using the IP protocol.
■
All ports on slots 1 and 3 have been assigned.
■
IP address 192.207.35.1.
■
Personnel
●
Protocol-sensitive VLAN using the IP protocol.
