Another question about IOS LSP is that if there is a
way to limit LSP only for BGP?
I know in JUNOS, by the default only BGP uses LSP for
network-hop either with short-cut or not, then you
could advertise LSP into a specific IGP, is this the
same with IOS? I noticed that there is a command to
announce the LSP to IGP, does this mean all the IGPs
will start announcing this LSP?
Apparently I have not done my lab test, but as there
is not too many I could find from CCO, I hope I could
get some input from the list, so that I have an idea
what to expect in our lab test.
Thanks
