Greetings everyone!
We are trying to launch twamp light on the remote device connecting to ASR9k.
ASR9k has such configuration:
service ipv4 udp-small-servers max-servers no-limit TWAMP_REFLECTOR
ipv4 access-list TWAMP_REFLECTOR
10 permit ipv4 host 10.63.9.4 host 10.63.9.1
20 deny ipv4 any any
Remote device's source address is 10.63.9.4, destination address - 10.63.9.1 and destination port - 7. Pcap trace shows that ASR responding to remote device with ICMP port unreachable message.
ASR interface does not have any ACL configured.
What could be the reason?
Thank You.
