What about packet forwarding? Let’s see:Ħ4 bytes from 10.0.0.11: icmp_seq=1 ttl=64 time=0.448ms.ġ packet transmitted, 1 packet received, 0.00% packet loss Actually, in ISIS pure IPv4 routing was also working for unnumbered Ethernet interfaces without problems. Let’s see how to do it: Nokia (Alcatel-Lucent) SR OSĪfter the network has reconverged, we briefly check the routing table to confirm that: Then I decided to change routing protocol in my network, which my small service provide core actually, to OSPF. I’ve tried a lot of different options on my Cisco IOS XRv routers like enabling/disabling RSVP on interfaces, playing with different MPLS-TE and Segment Routing parameters, but unfortunately it hasn’t brought anything that solves this issue. Probably, it’s a bug or limitation of XRv itself or IOS XR version 6.1.2, I don’t know. Change of IGP from ISIS to OSPFĪs we have figured out in the end of the previous article, there Cisco IOS XR doesn’t generate information in MPLS TED (Traffic Engineering Database). I advise you to read it beforehand, so you will be synchronized with the actual state, what we are talking about. It’s continuation of the previous one, so we use the topology and existing configuration from that one.
