Fix Recommendation

Configure the router to authenticate MSDP messages as shown in the following example:

RP/0/0/CPU0:R2(config)#router msdp
RP/0/0/CPU0:R2(config-msdp)#peer x.14.2.1
RP/0/0/CPU0:R2(config-msdp-peer)#password clear xxxxxxxxxxxx
RP/0/0/CPU0:R2(config-msdp-peer)#exit
RP/0/0/CPU0:R2(config-msdp)#peer x.15.3.5
RP/0/0/CPU0:R2(config-msdp-peer)#password clear xxxxxxxxxxx
RP/0/0/CPU0:R2(config-msdp-peer)#end

Check Contents

Review the router configuration to determine if received MSDP packets are authenticated.

router msdp

remote-as nn
!
peer x.15.3.5
password encrypted 04500A140A2F
