I got my gig interface I created vlans, which means I get sub interfaces. For a point to point connection to a Juniper box it does work when i used an existing vlans (vlan created since a while but not used) but when I am creating a new vlan or sub interface I cannot see the remote host in my ARP table or I can see it but it desappear after few seconds..
The config is basic on the cisco box:
encapsulation dot1Q 705 ip vrf forwarding XXXXXX ip address XXXXXXX 255.255.255.252 no snmp trap link-status no cdp enable
With vlan705 I can see the remote host MAC in my ARP table
encapsulation dot1Q 790 ip vrf forwarding XXXXXX ip address XXXXXXX 255.255.255.252 no snmp trap link-status no cdp enable
With vlan 790 I can't or I see it for a few seconds and desappeared. Note I did try with new vlans 789 etc etc same issues.
Config on both sides have been check and re check. I mean it's a point to point which means it should be straight forward?
Is someone already got this type of bug? I mean there is a limit of vlans which hasn't been reach on the card and no errors-warning message in the logs.
