Frame-Relay over MPLS.pcap.cap (1.4 KB)

ICMP on a Frame-relay over MPLS link. If Wireshark doesn't understand it's FR, right click on a packet, select "Decode as" from the menu and select "Frame Relay DLCI PW" on the "MPLS" tab.

The OSPF metric is preserved and propagated within the MPLS cloud by the MP-BGP MED attribute.

Routers at 1.1.2.1 and 1.1.2.2 are PEs in a MPLS cloud. LDP starts at packet 8 and they build up a pseudo-wire VC (last FEC in packets 11 and 13). At packet 15 we already have STP running between CE1 and CE2 (two routers with ESW), encapsulated in 2 MPLS headers. All the ethernet stuff follows: CDP, ARP, ICMP between two hosts on the same subnet.
MPLS_encapsulation.cap (1.3 KB)
| Packets: 10 | Duration: n/a | Downloads: 4805 |
Capture taken from the PE1-P1 link. ICMP traffic between CE1 and CE2 is encapsulated outbound with MPLS label 18. Note that returning traffic is not labeled, due to penultimate hop popping (PHP).
