Modifying Neighbor Hello Messages
By default, the Hello messages sent by a PIM router to its neighbors contain a
generation identifier. The generation identifier is a random number that PIM
appends to Hello messages. This number remains static as long as the router is
active. A PIM router uses the generation identifier to quickly learn whether a
neighbor rebooted with the latest RP set information within the holdtime specified
in its previous Hello message.
You can prevent the PIM router from appending generation identifiers to Hello
messages that it sends to its neighbors. Disable this option if you have a network
in which Bay Networks and non-Bay Networks PIM routers are interoperating.
To disable and reenable the inclusion of generation identifiers in Hello messages,
complete the following tasks:
