[j-nsp] vlan tagging, vlan ids, etc.

[harry]

I do not see any problems with the configuration. Some Gig-E PICs have
firmware limitations on VLAN support in a CCC/L2 VPN environment, but I am
not aware of any issues with conventional VLAN tagging.

Have you tried:

1. Deactivating/reactivating the interface to see if a bounce resolves
(maybe try a commit full also)?

2. Looking in the log for any error messages?

3. I suspect the issue lies at the remote end, or in some intervening
device. Can you monitor traffic while pinging to confirm that traffic
(likely an ARP) leaves the interface with appropriate tagging/encapsulation?

This config works for me with two juniper boxes back-to-back:

[edit interfaces ge-0/3/0]
lab at San_Jose-3# show 
vlan-tagging;
unit 0 {
    vlan-id 1;
    family inet {
        address 10.222.29.2/24;
    }
}

[edit interfaces ge-0/3/0]
lab at San_Jose-3# run ping 10.222.29.1 count 1 
PING 10.222.29.1 (10.222.29.1): 56 data bytes
64 bytes from 10.222.29.1: icmp_seq=0 ttl=255 time=1.868 ms

--- 10.222.29.1 ping statistics ---
1 packets transmitted, 1 packets received, 0% packet loss
round-trip min/avg/max/stddev = 1.868/1.868/1.868/0.000 ms

And a dump on the local router while a ping is issued on the remote end:

[edit interfaces ge-0/3/0]
lab at San_Jose-3# run monitor interface ge-0/3/0.0 detail layer2-headers

Listening on ge-0/3/0.0, capture size 96 bytes

HTHs.
