Steps : EAG-4--NCS540-1--CSS1-NCS540-2--CSS2--AGG1 Verify the fec usage and encap usage on NCS540-2 first before do the below steps. MPLSNH will be around 10k. 1) On NCS540 node shut/unshut the down which are parts of erps and l3 link between NCS540-1--CSS1 2) check the usage of fec and encap on NCS540-2 node. or another sceanrio is reboot EAG-4 . Each time of reboot we will see an increase of mplsnh Each time increase in mpls nh is by 4k or 5k which eventually leads to more usage of mpls nh and errors. Encaupsuagehigh one text i have attached which has intial and after iteration ..logs.
