Hi,
There is an indirect connectivity between ASR 903 router and Cisco 3560CG router for which the configured to be in same IP segment. The two devices are not pinging from each other, but able to ping other devices from both which are in the same LAN segment.
Router:
-----------
interface Po4
service instance 600 ethernet
description COLLECTOR
encapsulation dot1q 600
rewrite ingress tag pop 1 symmetric
bridge-domain 600
interface BDI600
description COLLECTOR
ip address 100.66.44.9 255.255.254.0
no ip redirects
no ip unreachables

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 100.66.44.1, timeout is 2 seconds:

Switch:
-----------

Type escape sequence to abort.

One thing is in arp table of the switch, arp for that particular router is continuously flushing and always is "0". On the other end, in router there is
no problem, the arp for the switch is aging.
Warm Regards.
