Hi,
I am facing issues with route leaking!I used same configuration for route leaking on devices ASR 1004 and 12K IOS!
The problem is both giving different output!On 12K iam getting expected output on sh ip bgp vpnv4 all labels but on ASR iam not getting.In forwarding table ASR used POP action but in 12K aggregate !How to fix this!
12K#sh ip bgp vpnv4 all labels

hi giuseppe,
In the bgp routing table i can see route leaking happening..like
Route Distinguisher: 200:1 (vrfB)
172.3.3.3/32 1.1.1.1 nolabel/18
172.4.4.4/32 0.0.0.0 33/aggregate(vrfB)
172.5.5.5/32 0.0.0.0 nolabel/aggregate(vrfD)
vrf B learning vrf D
but in ASR
ASR1004#sh ip bgp vpnv4 all labels
Network Next Hop In label/Out label
Route Distinguisher: 200:1 (PRAMOD_IL)
7.7.7.7/32 0.0.0.0 nolabel/nolabel(PRAMOD_IL)
8.8.8.8/32 0.0.0.0 17/nolabel(PRAMOD_IL)
PRAMOD_IL is learning the same Is this also an expected behaviour?
In both above examples communication happening fine but on in bgp vpnv4 table getting different outputs!
