Can someone provide me the proper syntax to establish multiple OSPF instances (one per VRF)? I can set up the instances, but don't see any way to identify NETWORK entries as belonging to specific instances... I'm probably too Cisco indoctrinated.
I am running a backone OSPF instance tying my core MT routers together along with BGP and LDP as a mesh of PE nodes.
Assuming I want to link with my CE routers using OSPF over VLANs, how do I set up the separate OSPF instances to handle this? All of the examples assume static routing for the MPLS/BGP/LDP network and just use the single backbone OSPF instance for a single VRF... No examples show multiple VRFs.
Thanks,
Tim McKee
Re: Syntax Query
For example network 1.1.1.0/24 is in VRF table
Configuration below will make new ospf instance, new backbone area for that instance and add network to area
Configuration below will make new ospf instance, new backbone area for that instance and add network to area
Code: Select all
/routing ospf instance add name=myinstance
/routing ospf area add name=myarea area-id=0.0.0.0
/routing ospf network add area=myarea network=1.1.1.0/24
Re: Syntax Query
Code: Select all
/routing ospf instance add name="customer1"
/routing ospf area add area-id=0.0.0.0 instance="customer1"
# creates customer1-backbone
/routing ospf network add network=0.0.0.0/0 area="customer1-backbone"
Re: Syntax Query
Working now... Thanks for the help....
It actually works much better when you force a Cisco switch port into trunking mode if the link is on a Vlan... It's no wonder the OSPF neighbors wouldn't set up...

Re: Syntax Query
If you consider using MPLS in production, I'd like to share with you two handy macros that will help you in your provisioning:
First is to add an interface to an existing vrf:
This adds ether2.80 to vrf "customer1"
Second is to add a vrf to the BGP instance:
This adds vrf2 to the lists of vrfs to announce.
I found these handy as I don't have to recompile lists of interfaces or vrfs from within my provisioning system.
Enjoy!
First is to add an interface to an existing vrf:
Code: Select all
/ip route vrf set [ /ip route vrf find routing-mark=customer1 ] interfaces=( [/ip route vrf get [ /ip route vrf find routing-mark=customer1 ] interfaces ] . “,ether2.80”)
Second is to add a vrf to the BGP instance:
Code: Select all
/routing bgp instance set default vrf=([/routing bgp instance get default vrf ] . “,vrf2”)I found these handy as I don't have to recompile lists of interfaces or vrfs from within my provisioning system.
Enjoy!

superb, thanks!
