Hi Claudio & Co.,
I am running 4.3-current. I am using a very basic bgpd config
file that worked for 4.2 very well. Unfortunatelly, with
-current my router does not want to announce our prefix anymore.
Any ideas?
Thanks,
- Christian
Details: (my as: 303, transit: 304)
I am able to receive prefixes from my transit provider.
bgpctl shows the following (77.X.Y.0/21 being our prefix):
# bgpctl show rib 77.X.Y.0
flags: * = Valid, > = Selected, I = via IBGP, A = Announced
origin: i = IGP, e = EGP, ? = Incomplete
flags destination gateway lpref med aspath origin
77.X.Y.0/21 A.B.C.D 105 0 304 [SOMEAS] 303 i
I* 77.X.Y.0/21 77.X.Y.2 100 0 i
AI 77.X.Y.0/21 0.0.0.0 100 0 i
So there are two funny things:
- I get my own prefix (announced by our other router, 77.X.Y.2)
via the transit provider.
- The line with my announced prefix ("AI") is missing the "*".
2# bgpctl network show
flags: S = Static
flags destination
* 77.X.Y.0/21
