[mpls-linux-general] cisco

[Kauder T. <Tho...@ic...>]

Hi Jim,
I'm testing the LDP now against a Cisco Router.
No Session is established, sorry.
I turned on full tracing and sniffed using ethereal.
The Cisco doesn't send a configuration sequence number (TLV)
LDP_Linux therefor doesn't accept the Hello-packets.

If I understand RFC 3036 right the CSN is optional !!!

Here's part of the ldp output:

OUT: ## args    Hello msg does not have Csn TLV
OUT: ## args Mesg size: 24 (34)
EXIT: ## args ##
ENTER: ## args ##
ENTER: ## args ##
ENTER: ## args ##
OUT: ## args Hello Recv: entity(2)
ENTER: ## args ##
EXIT: ## args ##
EXIT: ## args ##
ENTER: ## args ##
EXIT: ## args ##
EXIT: ## args ##
EXIT: ## args ##
EXIT: ## args ##
ENTER: ## args ##
Incoming: want(10) size(0) current_size(0)
UDP data size = 0
EXIT: ## args ##
OUT: ## args ldp_event: FAILURE executing a CLOSE
ENTER: ## args ##
EXIT: ## args ##
EXIT: ## args ##                                      

Is that a bug or what ?

greetings

Thorsten
