rgds, Alaerte =================================================== Date: Mon, 18 Jun 2007 22:26:26 +0300 From: Georgi Yalamov <[EMAIL PROTECTED]> Subject: [j-nsp] Carrier of Carrier VPNs To: [email protected] Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset=windows-1251; format=flowed Dear fellows, If anybody can help me or can give me an advice I'll be very grateful. I had strange problem with Carrier of Carrier VPN using Juniper M320 provider core with junos 8.1R1.5 and Cisco Catalyst 6506 Sup720+ OSM. I'm using LDP and OSPF between CE-PE and PE and the only problem is that LDP between cisco and juniper is down. Here is a small scheme: CE-PE -------------------P-PE-------MPLS cloud---------P-PE---------------CE-PE MSR11 65-R 72-P MSR20 Cisco M320 M320 Cisco The unnormal here is that i try this with several ciscos as CE-PE like 28xx, 3800 with all kind of configurations for LDP, targeted neighbors and etc but the result was the same - no ldp between CE-PE and P-PE. I'll done all this with another P-PE devices - routers in LAB with the same hardware, same protocol protocols and instances configurations and it is working. Also it is working when replace connection between ciscos with direct VLAN. I'm sure that the problem is not in MTU and LDP timers but... Here is some logs if they are interesting for someone.
