Configuring OSPF
ExtremeWare XOS 10.1 Concepts Guide 197
In this configuration, all IP traffic from stations connected to slots 1 and 3 have access to the router by
way of the VLAN Finance. Ports on slots 2 and 4 reach the router by way of the VLAN Personnel. All
other traffic (NetBIOS) is part of the VLAN MyCompany.
The example in Figure 36 is configured as follows:
create vlan Finance
create vlan Personnel
create vlan MyCompany
configure Finance protocol ip
configure Personnel protocol ip
configure Finance add port 1:*,3:*
configure Personnel add port 2:*,4:*
configure MyCompany add port all
configure Finance ipaddress 192.207.35.1
configure Personnel ipaddress 192.207.36.1
enable ipforwarding
configure rip add vlan all
enable rip
Configuring OSPF
Each switch that is configured to run OSPF must have a unique router ID. It is recommended that you
manually set the router ID of the switches participating in OSPF, instead of having the switch
automatically choose its router ID based on the highest interface IP address. Not performing this
configuration in larger, dynamic environments could result in an older link state database remaining in
use.
Configuring OSPF Wait Interval
ExtremeWare XOS allows you to configure the OSPF wait interval, rather than using the router dead
interval.
CAUTION
Do not configure OSPF timers unless you are comfortable exceeding OSPF specifications.
Non-standard settings might not be reliable under all circumstances.
To specify the timer intervals, use the following commands:
configure ospf area <area-identifier> timer <retransmit-interval> <transit-delay>
<hello-interval> <dead-interval> {<wait-timer-interval>}
configure ospf virtual-link <router-identifier> <area-identifier> timer
<retransmit-interval> <transit-delay> <hello-interval> <dead-interval>
{<wait-timer-interval>}
