Hi Community
I do have a question about OSPF
If u look at the attachment you will find 2 loopbacks interface on Router R3
if I want to reach the Loopback0 and Loopback1 from R5 the path will be R5-R1-R3
Is it possible to change the path only for one Loopback and keeping the same old path for other Loopback
example
R5 to Loopback 0 will go throuth R3
R5 to Loopback 1 will go through R1-R3
I can do this with Static Route but i hope if you have another suggestions.
Thanks in Advanced

Hi @IeSa50839 ,
There is two ways I can think of.
1. Put the link from R3 and R5 in area 0 and R3 Lo0 in area 0. Put the link from R1 to R3 and the link from R1 to R5 and R3 Lo1 in non back bone area. This way traffic from R5 to R3 Lo0 will travel directly to R5 and traffic from R5 and R3 Lo1 will use the non backbone area path through R1.
2. Configure an MPLS traffic engineering tunnel going from R5 to R3 via R1 and configure R3 Lo1 to be reachable using that tunnel.
