S6700 Series Ethernet Switches
Configuration Guide - IP Routing
As shown in the routing table, Switch B learns the route to the network segment 10.3.1.0 through
BGP, and the outgoing interface is Vlanif40. The routes to the network segments 10.1.2.0 and
10.1.4.0 respectively can be learned through OSPF. The costs of the two routes are 2.
Step 7 Enable OSPF-BGP linkage on Switch B.
[SwitchB] ospf 1
[SwitchB-ospf-1] stub-router on-startup
[SwitchB-ospf-1] quit
[SwitchB] quit
Step 8 Verify the configuration.
# Restart Switch B.
<SwitchB> reboot

# View the routing table of Switch B. As shown in the routing table, only OSPF routes exist in
the routing table temporarily and their costs are equal to or greater than 65535. This is because
IGP route convergence is faster than BGP route convergence.

NOTE
Confirm the action before you use the command because the command leads to the breakdown of the
network in a short time. In addition, when restarting a switch, ensure that the configuration file of the
switch is saved.
