Hello, everyone.This is my topology:My goal is for CE1 to ping CE2. Both have two subinterfaces (one for VLAN 10 and one for VLAN 20)CE1 example:interface GigabitEthernet1.10 encapsulation dot1Q 10 ip address 192.168.10.1 255.255.255.0 interface Gi...

Hello, everyone.I've began studying for MPLS L2 VPNs and there are a lot of different terms that describe different and sometimes even the same things.One of the terms that I don't fully grasp is the difference between a pseudowire and an EVC.A pseud...

Hello, everyone.A book I am reading about MPLS (MPLS Fundamentals) states this regarding a possible customer site interconnection:Often, customers do not want their sites to have full interconnectivity. This means they do not want or need the sites t...

Hello, everyone.When we implement OSPF as our PE-CE routing protocol and the customer has a backdoor link, our PE routers can actually use that backdoor link to reach a prefix. In my example here:R1 learns of the 40.40.40.40/32 prefix via both OSPF a...

Hello, everyoneWhen running MPLS L3 VPN, different PE-CE protocols can be used and different scenarios have to be taken into consideration.I have this topology here. The configuration part doesn't matter, the customers are running EIGRP everywhere (e...

Hello M02@rt37!Why would we want to force traffic through the hub PE? That's the confusing part to me. We are only diverting the flow of traffic, we aren't actually passing the traffic through a firewall or anything like that. I don't think I underst...

Hello,Thank you for the reply.I unfortunately can't quite wrap my head around this, maybe I am missing something here. Would it be possible for you to elaborate more on this, please?David

Hello,Thank you so much. So the route-map and route-policies are only to match prefixes that should have the SoO set? So it doesn't necessarily filter them?Is there any point in using them, then? Since the neighbor command will just tag everything.//...

Hello,The HW is Cisco 8011 Series Fixed 1RU Router 4x100G, 24x1/10/25G, 4xCu. The version running is Cisco IOS XR Software, Version 26.2.1 LNT.Thank youDavid

Hello!I suppose you're right. However, if the receiving router believed the different transport addresses to be different peers, shouldn't it build a TCP connection to each one, then?I've been thinking, each hello has the LSR's ID in it, so it knows ...
