Hi, I have a point to point link between 2 Cisco 7200s that I'm being required to add VLAN tagging to. Here are the interface configs:
interface FastEthernet5/0 no ip address duplex full ! interface FastEthernet5/0.253 encapsulation dot1Q 253 ip address xxx.xxx.xxx.249 255.255.255.252
interface FastEthernet4/0 no ip address duplex full ! interface FastEthernet4/0.253 encapsulation dot1Q 253 ip address xxx.xxx.xxx.250 255.255.255.252
However, when AT&T forces tagging on the ports, I cannot ping from .249 to .250, and AT&T cannot see my MAC address on their switches inbetween and zero traffic on the VLAN.
Does anyone have any ideas?
Router A is a 7206VXR running 12.2(4r) Router B is a 7204VXR running 12.2(12a)
