Hi All,
Trying to implement a really simple remote triggered blackhole config on
JunOS 5.1R3.4
Seems like it does not like the next hop (1.1.1.1) that I specify in the
policy because the prefixes that I am receiving marked with community
blackhole are all hidden. Is it not supported in this JunOS version.
Below is an example configlet:
term "bhole" {
from community blackhole;
then {
local-preference X;
community add Y;
community add Z;
next-hop 1.1.1.1;
accept;
}
}
