hi, all:
a while ago there was a thread about configuring a gre tunnel to be able to
run nlsp over a multipoint
interface. i was reviewing the suggested solution to this problem on my
friend's lab and was not able to make it work.
mind you, i did try the archives and tried the same setup with rip (that one
worked), so i was wondering if someone here can tell me what to tweak to get
this thingy to work.
my configs are below:
r1

see how the ethernet works just fine, but the tunnel doesn't:

does anybody have a sample config with show commands that actually worked?
