Hi Group,
I've troubles testing the correct operation of QPPB, which a very basi
setup:
Two eBGP neighbors, the second one of which is sending a route
10.8.4.0/22with community 30:2
The receiving neighbor should map that community route(s) to ip precedence
"flash-override".
Some show commands on the receiving neighbor:
R2#sh ip bgp 10.8.4.0
BGP routing table entry for 10.8.4.0/22, version 2
Paths: (1 available, best #1, table Default-IP-Routing-Table)
Advertised to update-groups:
2
7 307 8, (aggregated by 7 192.168.7.7), (Received from a RR-client)
172.30.200.7 (metric 20) from 172.30.1.5 (192.168.5.5)
Origin IGP, metric 0, localpref 100, valid, confed-internal,
atomic-aggregate, best
Community: 30:2
Community receieved, now let's check the routing table:
R2#sir 10.8.4.0
Routing entry for 10.8.4.0/22
Known via "bgp 65245", distance 200, metric 0
Tag 7, precedence flash-override (4), type internal
Last update from 172.30.200.7 00:03:49 ago
Routing Descriptor Blocks:
* 172.30.200.7, from 172.30.1.5, 00:03:49 ago
Route metric is 0, traffic share count is 1
AS Hops 3
Route tag 7
According to the output above, we successfully have mapped this route to
flash-override precedence.
Now, for testing it let's assign an access-list permiting only that
precedence out this interface:
interface Serial0/1/0.2 multipoint
ip address 172.30.1.2 255.255.255.248
ip access-group 101 out
bgp-policy destination ip-prec-map
[...]
Ping from a third router, going through our routers is unsuccessfull.
Any ideas why is that behaviour? I have cef enabled globally!
