Hello Guys,
Let's say I have three routers : R1, R2, and R3.
R1 is connected to R2, and R2 is connected to R3, so R2 is the router sitting in the middle and interconnecting R1 and R3.
R1 IP Loopback address : 1.1.1.1
R2 IP Loopback address : 2.2.2.2
R3 IP Loopback address : 3.3.3.3
Which command can I use on Router R1, to verify inside the ISIS database, that R2 (specifically) is advertising the loopback of R3.
I know if I check the routing table I will see it, but I want to check that information inside the ISIS database. Also I do not want to check the whole ISIS database but only the part of the database which is related to R2.
Thanks
