I have a problem configuring multi vrf ce, so I searched on the web for a document that can show me how to do that. I got this document from the net âDesigning MPLS Extensions for Customer Edge Routersâ. url:http://www.cisco.com/warp/public/cc/pd/rt/2600/prodlit/1575_pp.pdf
I don't understand the ip address used there, on page 13 under router BGP 1 the ip add on neighbour 10.13.1.48 isn't that a network address(because if they use a mask 30 then it should be a network address)? Another question on that address still for which router is this address?
On page 17 and 18 for router 2621-ce configurations, is there a specific reason they used loopback mask of 30 instead of 32. On router BGP 3 they used update source of Ethernet is there s specific reason why the used the ethrnet? Why all these loopback since I don't see any loopback attached to any vrf?
The configs between the VXR and RSP-PE-EAST-4 are not included in this document, I wish I could see them. I see a VXR is showing vrf 15 and the tables on figure 8 shows v15, does this mean the VXR and 2611-CE-5 is on the same vrf?
Does any body have or know any document that I can read regarding the multi-vrf ce?
Your assistance would be greatly appreciated.
let's start from figure 8 the multi VRF device has multiple VRFs associated on the right side to conventional CE routers and on the left side to the PE node.
For each VRFliteX there is a link on the right of the multiVRF CE and a link on the left towards PE node.
So the multiVRF CE has multiple address-families ipv4 vrf VRFname.
Actually it has multiple OSPF processes one for each VRF.
In each address-family IPv4 vrf vrfname the multiVRF CE is redistributing into BGP the routes learned on the dedicated OSPF process.
So your understanding is correct.
If we look at a specific VRF vrflite3 for example the configurations of the other VRFs have no impact on it.
they are segregated. The document shows also the capability to support overlapping IP addresses in different not communicating VRFs.
Hope to help
