A router ID is required when configuring virtual links. This router ID must be the
same one specified as the target virtual neighbor (nbr) on switch 1 in Step 8 on
page 573.
RS G8264(config)# ip router­id 10.10.14.1
RS G8264(config)# router ospf
RS G8264(config­router­ospf)# enable
This version of ENOS requires that a backbone index be configured on the
non‐backbone end of the virtual link as follows:
RS G8264(config­router­ospf)# area 0 area­id 0.0.0.0
RS G8264(config­router­ospf)# area 0 enable
RS G8264(config­router­ospf)# area 1 area­id 0.0.0.1
RS G8264(config­router­ospf)# area 1 type transit
RS G8264(config­router­ospf)# area 1 enable
RS G8264(config­router­ospf)# area 2 area­id 0.0.0.2
RS G8264(config­router­ospf)# area 2 type stub
RS G8264(config­router­ospf)# area 2 enable
RS G8264(config­router­ospf)# exit
RS G8264(config)# interface ip 1
RS G8264(config­ip­if)# ip ospf area 1
RS G8264(config­ip­if)# ip ospf enable
RS G8264(config­ip­if)# exit
