Hi All,
I am facing lot of challenges related to CEF issue in IOS-XR. Router shows Glean adjacency for connected IP subnets.
Sometime issue gets resolved by rebooting routers, but many a times it doesn't get resolved even after doing so.
To troubleshoot the same, we have done many steps like Clearing Arp, CEF table, adding static ARP entry, putting static routes etc etc; but no luck.
Can someone please help me to know that what is the root cause of the issue and the remedy of same.
I am preparing for CCIE SP Lab, and the challenge is that reboot of router is not allowed during exam. EVen if it will be allowed, then not sure that whether it will get resolved.
Please help.
Below is the details of IOS-XR image for reference.
