MPLS tagging VPNv4
* Normally, there are 2 MPLS tags. However, in this scenario, there is an implicit null on the outer layer so it will pop out left only VPN tag.

Dear Everyone,
ReplyDeleteAs I just visited your with really good sample of many network labs configuration. Did you have posted the topic related to sample config MPLS with IS-IS via route reflector by BGP?
