Hello! My apologies for the incoming wall of text! We have a medium sized SP network running MPLS on ASR9K routers in our core and at our edges. I was able to consolidate the responsibilities of our edge routers by bringing them into the underlay net...

Hello! I have several IOS-XR routers and have been monitoring them with SNMPv3 for quite some time. We have them configured with an OSPF underlay with LDP, and then use L3VPNs/VRFs for public internet interfaces. I am running into a problem using SNM...

Hello! I work for a mid-sized ISP and we have an MPLS core consisting of ASR9K, ASR903, and ASR920 devices. We use OSPF and LDP. Currently, we have a VRF for internet traffic, which uses a L3VPN and BGP to get around our network. Our edge connections...

Hello! I work for a regional ISP and I have a pretty complicated problem that I would like some feedback on. I am in the process of migration our upstream internet peers to a new border VRF L3VPN in our MPLS core. Currently our public ASN is being ad...

Hello! Apologies, as this will likely be a lengthy post. I work for a regional ISP with multiple upstream internet connections and multiple customers that BGP peer with our AS and share their prefixes to the internet through us. Currently, we have ...

Thank you for your reply! I added that in, however, I think these lines are more for sending traps from the router to a destinantion. I am trying to allow a server to SNMP walk our router, initiating the connection from the server. I opened a TAC cas...

Upon further inspection, the command on the ASR900 devices with 16.X is: no mpls ip propagate-ttl The IP got me....yet again... Thank you very much for the reply! Your response caused me to look deeper to find the solution!

It actually seems to only be assigning a label to prefixes learned locally on the router. Since this is the case, I am able to just make this change on our border routers, but I can leave our route reflectors as-is since they aren't locally learning ...

It seems that the global commands in the links have been changed (these particular routers are running ios-xr 64-bit 6.5.3), but i found that this can be set on the individual VRF. This way I should be able to make the change only for VRF BORDER, whi...

I was able to get around my problem. I configured a confederation ID on my upstream peering routers with my public AS. I only have one private AS in our network, so I didn't need to configure any additional confederation peer AS's. Neighbors using th...
