Hi all,
I've been working on QPPB configs in dynamips. I am trying to build it into
my completed version of IP Expert's lab 8 from the workbook. Here's what
I've setup:
R1 & R3 are both configured with similar settings for community tagging
towards R10:
route-map AS105_OUT permit 20
match ip address prefix-list SETPREC2
set community 105:1002 additive
set mpls-label
!
route-map AS105_OUT permit 30
match ip address prefix-list SETPREC3
set community 105:1003 additive
set mpls-label
!
ip prefix-list SETPREC2 seq 5 permit 123.123.123.1/32
ip prefix-list SETPREC2 seq 10 permit 123.123.123.2/32
!
ip prefix-list SETPREC3 seq 5 permit 123.123.123.3/32
*R10 sees the communities just fine:*
R10#show ip bgp community 105:1002
BGP table version is 34, local router ID is 105.105.105.10
Status codes: s suppressed, d damped, h history, * valid, > best, i -
internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
* 123.123.123.1/32 105.123.103.3 50 0 123 ?
*> 105.123.101.1 0 0 123 ?
* 123.123.123.2/32 105.123.103.3 50 0 123 ?
*> 105.123.101.1 0 123 ?
R10#show ip bgp community 105:1003
BGP table version is 34, local router ID is 105.105.105.10
Status codes: s suppressed, d damped, h history, * valid, > best, i -
internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
* 123.123.123.3/32 105.123.103.3 0 50 0 123 ?
*> 105.123.101.1 0 123 ?
Here's the bgp table map implemented on R10:
R10#show route-map QOPPB
route-map QOPPB, permit, sequence 10
Match clauses:
community (community-list filter): PRE2
Set clauses:
ip precedence immediate
ip qos-group 2
Policy routing matches: 0 packets, 0 bytes
route-map QOPPB, permit, sequence 20
Match clauses:
community (community-list filter): PRE3
Set clauses:
ip precedence flash
ip qos-group 3
Policy routing matches: 0 packets, 0 bytes
The Table Map seems to be working as expected:
R10#show ip route 123.123.123.1
Routing entry for 123.123.123.1/32
Known via "bgp 105", distance 20, metric 0
Tag 123, precedence immediate (2), qos-group 2, type external
Last update from 105.123.101.1 00:10:16 ago
Routing Descriptor Blocks:
* 105.123.101.1, from 105.123.101.1, 00:10:16 ago
Route metric is 0, traffic share count is 1
AS Hops 1
R10#show ip route 123.123.123.2
Routing entry for 123.123.123.2/32
Known via "bgp 105", distance 20, metric 0
Tag 123, precedence immediate (2), qos-group 2, type external
Last update from 105.123.101.1 00:10:19 ago

AS Hops 1
R10#show ip route 123.123.123.3
Routing entry for 123.123.123.3/32
Known via "bgp 105", distance 20, metric 0
Tag 123, precedence flash (3), qos-group 3, type external
Last update from 105.123.101.1 00:10:20 ago
Routing Descriptor Blocks:
* 105.123.101.1, from 105.123.101.1, 00:10:20 ago

AS Hops 1
However, when I source pings from any of the above 3 loopbacks and send them
over to R5, I don't see any matches on R10's interface facing R5:
interface FastEthernet0/0.510
encapsulation dot1Q 510
ip address 105.10.5.10 255.255.255.0

I am curious if I'm doing something wrong here or if this is just Dynamips
acting funky. I set this up in one other Dynamips lab and had similar
results.
Thanks in advance,
Eric
