I have configured an mpls vpn between two customer's sites. In every site I have installed two cat35xx with a multi-vrf ce.
I have a multi access ospf neighbour ship to the customer equipments and a bgp session to mpls backbone.
The ospf routes are redistributed on bpg and vice versa.
On ospf process can I use domain-tag to prevent routing loop?
How can i do to verify the domain-tag's functionality in this architecture?
I've tried to configure domain-tag but the ospf database contains all tagged routes but how can i be confident that these routes'll not be announce back to mpls backbone through bgp session between catalyst 35xx and Pe?
Is the the domain-tag functionality supported with vrf-lite?
Thanks in advance
