Hi,
Recently we did a lab setup of EVPN E-tree scenario in ASR9K, IOS-XR 6.4.2. The following topology was built,
(EVI 504) --- AC2 (Leaf) --- CE2
/
CE1 --- AC1 (Leaf) --- PE1 (EVI 504) --- PE2
\
(EVI 505) --- AC3 (Root) --- CE3
The following configuration was used regarding EVI's;
evpn
evi 504
bgp
route-target import 1234:50501
route-target export 1234:50502
!
control-word-disable
advertise-mac
!
evpn
evi 505
bgp
route-target import 1234:50502
route-target export 1234:50501
!
control-word-disable
advertise-mac
bvi-mac
!
With this config in place, CE3 could communicate with CE1, but CE3 could not communicate with CE2, i.e. routes was not exchanged between the two EVI's in the same PE (PE2) router. (When using the similar config for L3VPNs/VRF's its no problem). Has anyone any experience with this kind of setup?
Best Regards
