I was looking for the Purge origin Identifier tlv #13 in ISIS thats sent by a router whenever a LSP needs to be purged from the network. I tried isolating a router by shutting down the interface connecting to rest of the area. Now I took packet capture on the rest of the routers but when the LSP with Remaining Lifetime 0 was captured there was no tlv #13 in the LSP that was flooded in the rest of the Area.
The routers used were Cisco 7200. I didn't found any isis setting on router to enable this. Is it supported after certain IOS release?
R3#sh version
Cisco IOS Software, 7200 Software (C7200-ADVENTERPRISEK9-M), Version 15.1(3)S, RELEASE SOFTWARE (fc1)
