We are running an 100Mb Ethernet circuit from Site A to a core network hub Site B
We have no VLAN at site A
We have VLAN 506 at site B
We are trying to use Service Instances to POP VLAN from the A end, but can only see one direction
A ping to 255.255.255.255 from the CPE succeeds A End, in that it is heard on the subinterface at the core B End. Pinging from the CPE to the core fails, as the next hop ARP entry is listed as Incomplete.
The core has a valid ARP entry for the CPE, but pinging from the core to the CPE does not reach the customer site.
It appears that tags are being stripped somewhere unidirectionally. Config below.

[toc:faq]The ProblemOn traditional switches whenever we have a trunk
interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
[toc:faq]Introduction:Netdr is a tool available on a RSP720, Sup720 or
Sup32 that allows one to capture packets on the RP or SP inband. The
netdr command can be used to capture both Tx and Rx packets in the
software switching path. This is not a substitut...
IntroductionOSPF, being a link-state protocol, allows for every router
in the network to know of every link and OSPF speaker in the entire
network. From this picture each router independently runs the Shortest
