Lab 4, label problem
IN Lab4, to setup InterAS peering for VPNv4, VPNv6 and MDT, I am trying to get label swtiching between XR10 and R4. I am using online Remote Lab. I could not get ebgp peering between R4 and XR2. R4 and XR2 can't communicate. ping and traceroute failed. At that time, I used bgp send-label for Inter and Intra. Actually, I worked on 1st day. I failed starting on 2nd day. On 1st day, I can traceroute and I could see MPLS label. But, starting next day, I could not trace but I can see label.
Finally, I choosed the same method of workbook. I redistribute bgp routes into ISIS. I noticed I get remote label (AS2000) via R5 but I can't get via XR1. If I shut down link of XR1 to R3, I can see all labels via R5. As I am redistributing into IGP, all routers have all routes. So, I can communicate between XR2 and R4 but it is not label switching if XR1 is on the way.
I tried several time but still can't. Is there any other method I can troubleshooot? I don't know why I can't get label via XR1.
