The EoIP tunnel between anchor and foreign controllers is not functioning.
Which two ports and protocols must be open to enable the tunnel to form? (Choose two.)
A . IP 97
B . UDP port 5246
C . UDP port 16666
D . UDP port 1646
E . UDP port 5247
Answer: AC
Explanation:
ports 16666 (16667 if using secure mobility) and protocol 97 must be allowed bidirectionally between the IP addresses of the controller management interfaces.
– UDP 16666 for tunnel control traffic
– IP Protocol 97 for user data traffic
