host1(config)# ip vrf ospf2
Proceed with new VRF creation? [confirm]
host1(config-vrf)#
rd 100:85
host1(config-vrf)# exit
2.
Start OSPF on the VRF, either from the parent VR or directly from the VRF.
From the parent VR:
host1(config)# router ospf 5 vrf ospf2
From the VRF:
host1(config)# virtual-router :ospf2
host1:default:ospf2(config)# router ospf 5
The command prompts in the remaining steps reflect using the latter method
for starting OSPF.
3.
Configure the OSPF domain ID.
host1:default:ospf2(config-router)# domain-id 45
4.
Configure the VPN route tag.
host1:default:ospf2(config-router)# domain-tag 1200
5.
Redistribute routes learned from other PE routers back into OSPF.
host1:default:ospf2(config-router)# redistribute bgp
6.
Create an address family in BGP.
host1:default(config)# router bgp 100
host1:default(config-router)# address-family ipv4 unicast vrf ospf2
7.
Redistribute OSPF routes into BGP.
host1:default(config-router)# redistribute ospf
domain-id
■
Use to set the OSPF domain ID for an OSPF VRF on a PE router; the default value
is zero.
■
Use the same domain ID for all OSPF VRFs in a given OSPF domain.
■
When the value is zero, MP-BGP does not attach an OSPF domain identifier
attribute when it converts an OSPF route to an MP-BGP route to cross the
BGP/MPLS VPN.
■
Example
host1:default:ospf2(config-router)# domain-id 45
■
Use the no version to restore the default value.
■
See domain-id.
