Hi,
I have an issue with ME3600 running 15.3(1)S. I have a BDI used for CPE
management.
cisco ME-3600X-24FS-M
Cisco IOS Software, ME360x Software (ME360x-UNIVERSALK9-M), Version
15.3(1)S, RELEASE SOFTWARE (fc1)
This is the BDI and VRF configuration:
interface Vlan1620
ip vrf forwarding 65000:1620
ip address 10.232.28.1 255.255.252.0
no ip redirects
ip vrf 65000:1620
rd 65000:1620
route-target export 65000:1620
route-target import 65000:1620
address-family ipv4 vrf 65000:1620
redistribute connected
The MPLS part is working fine, no issues there. There is also a DHCP
pool handing out IPs to the CPEs.
ip dhcp pool 65000:1620
vrf 65000:1620
network 10.232.28.0 255.255.252.0
domain-name xyz
default-router 10.232.28.1
option 66 ascii 10.232.28.1
dns-server 8.8.8.8
lease 0 0 30
This also works fine and I have verified that CPE has both IP and GW.
Then for the service instance configuration:
interface GigabitEthernet0/5
switchport trunk allowed vlan none
switchport mode trunk
service instance 1620 ethernet
encapsulation dot1q 1620
rewrite ingress tag pop 1 symmetric
bridge-domain 1620
interface GigabitEthernet0/11
switchport trunk allowed vlan none
switchport mode trunk
service instance 1620 ethernet
encapsulation dot1q 1620
rewrite ingress tag pop 1 symmetric
bridge-domain 1620
Traffic to CPEs behind Gi0/11 works:
sh ip arp vrf 65000:1620 vlan 1620 | i 29.26
Internet 10.232.29.26 0 0022.07f3.3450 ARPA Vlan1620

Traffic to CPEs behind Gi0/5 does not work.

Pinging 10.232.28.190 with 32 bytes of data:
Request timed out.

Request timed out.
This is also confirmed by looking at counters. There seems to be no
egress traffic on Gi0/5.

It does work to ping locally from the 3600 though:
ping vrf 65000:1620 10.232.28.190
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.232.28.190, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
I'm not sure how to troubleshoot it further. I've also tried setting up
ERSPAN sessions for RX traffic on Gi0/5 but I don't get anything in
unless I ping 28.1 which is the IP of the interface on the 3600.
Any clues?
