A present network scenario, i have a core router (VXR A) with a link connected to MPLS network M-1 Router an e-BGP (instance X), all the customer connected to MPLS network uses instance X of M-1 to VRX A for Internet reach ability.
Now changed for high availability network, i will be adding new Core Router VXR B. For this, VXR B will also be connected with MPLS network M-1 router an e-BGP (Instance Y), we have numbers of customer connected to our MPLS network example Customer A and Customer B, my requirement is that both the instance M-1 to VXR A and M-1 to VRX B should be on Active that means Customer A should be going through Instance X and Customer B should be going through Instance Y. In case of link failure between any VXR (A and B) to M-1, route of any customers should be going through the live one instance.
Here by I have also attached the network diagram.
Hopping for your help for implementing such network scenario.
For each eBGP session, you could set a different BGP community for the default-route so the remote PE could set a different local-pref based on the community. It will allow you to load-balance your customers on both SP and provide redundancy as well.
I am not much good in MPLS VRF and its route policy. As of now our MPLS network is very simple, all the customers are bounded in single Instance ( instance X). I am not getting the exact clue how to accomplish the above scenario. Could you please guide me providing the configuration in sort ( simple example) and the related link.
We have all our customers are in VRF let's say vrf link_X (a single VRF), now we are adding one more vrf let's say vrf link_Y. And also all the customers are connected with Static VRF (static PE-CE).
The main thing is customers with the VRF link_X uses Instance_X primary for internet traffic and Instance_Y for backup and the customers with the VRF link_Y uses Instance_Y for primary path and Instance_X for backup.
I have also attached our exact network diagram herewith.
For outgoing traffic :
As per Giuseppe -
whenever M-1 receives default route from Link X (in Instance_X) and from Link Y ( in Instance_Y) it tag the community 65xx:101 and 65xx:102 respectively.
As per Laurent -
On any other PE (M-x) routers will import the RT of both Instance_X and Instance_Y.
If route with the community 65xx:101 than set the Loc-Pref higher (200) otherwise, make it default for the Customers with the VRF link_X.
If route with the community 65xx:102 than set the Loc-Pref higher (200) otherwise, make it default for the customers with the vrf link_Y
And finally import it on the appropriate VRF table.
Am I right ?
I will deploy it on our regular maintains day and update you consequently.
