Hi everyone,
I was wondering if anyone has used QPPB on a interface that is in a VRF on the ASR9K
I have setup my BGP Policy and applied it to BGP under the vrf instance. I have confirmed in CEF that prefixes that match the community has the right classification.
0.0.0.0/0, version 9451648, proxy default, internal 0x4000021 (ptr 0xad3a0294) [1], 0x0 (0x0), 0x0 (0x0)
Updated Nov 25 22:38:10.135
Prefix Len 0, traffic index 0, precedence routine (0), priority 3
IP Precedence: 3
via xxxxx, 3 dependencies, recursive [flags 0x0]
path-idx 0 [0xad3c2884 0x0]
next hop xxxxx
I am classifying traffic from the inside outbound as it enters the inside interface as follows
ipv4 bgp policy propagation input ip-precedence destination
I have applied an input shaping policy under the interface so that all traffic that matches Prec 3 is shaped down to 25M as it enters the interface but I’m not seeing any matches on the policy. If I apply the same policy as egress on the opposite side of the router as the traffic leaves I can see the matches.
This would indicate that my classification is working but the shaping is applied before qppb classifies the traffic instead of after it is classified.
Here is the config
route-policy BGP-QPPB-SET-QOS-PREC
if community matches-any (100:103) then
set ip-precedence 3
else
if community matches-any (100:102) then
set ip-precedence 2
else
set ip-precedence 0
endif
endif
end-policy

If I do the following I do see matches on the policy for Prec 3 traffic, But I dont realy want to shape outbound as the external interface is a shared interface where many customers traffic will pass across.
