Packet Captures
packet-c.cap 675.0 KB
Submitted Jan 31, 2012 by Slaingod
This is a packet capture from a SonicWall. We were troubleshooting DHCP packet flows. The SonicWall saw the DHCP Discover and Sent an Offer. We never saw the DHCP acknowledgement. In the adjacent core stacked switching we were running "debug ip dhcp server packets" we only saw discover packets from IP phones up to the SonicWall. For some reason the SonicWall could not let any other DHCP packets through or out of it INSIDE (LAN) interface. Even if we put an ANY-ANY ALC for that interface. We ended up having to replace the SonicWall and upload the configuration from the old SonicWall to the new one.

4-byte_AS_numbers_Mixed_Scenario.cap 414 bytes
Submitted Apr 30, 2010 by pierky
Router "B" (AS 2) at 172.16.3.2 does not support 4-byte AS numbers, while router "A" (AS 10.1 / 655361) at 172.16.3.1 does.
Router "A" receives an UPDATE for the 40.0.0.0/8 subnet from an external router ("D") in the AS 40.1 / 2621441 (not shown), and it forwards it to "B" (pkt n. 2): AS_PATH contains "23456 23456" (the first stands for AS 10.1, the second for the originating AS 40.1), but NEW_AS_PATH contains the real 4-byte AS numbers.
At pkt n. 3 "B" receives the same subnet directly from "D" and sends it to "A", including the original NEW_AS_PATH attribute previously appended by "D".

4-byte_AS_numbers_Full_Support.cap 1.2 KB
Submitted Apr 30, 2010 by pierky
Router at 172.16.1.2 (hostname "D", AS 40.1 / 2621441) clears a previous established peering with 172.16.1.1 (hostname "A", AS 10.1 / 655361); They both support 32-bit ASN.
While opening the new session, they negotiate the "Four-octet AS Number Capability" (pkts n. 2 and 3).
Then, both "A" and "D" send some UPDATEs containing 4-octect encoded AS_PATH attributes (pkts n. 6 and 9). Please note: WireShark may show wrong paths unless you force 4-byte encoding in the Preferences / Protocols / BGP options.
