I have a problem in MPLS route leaking. First let me describe my network.
I have a network which includes 3 7609s and two 2800 series routers. Two 7609s act as PE/P and one 7609 work as PE and the 2800 series work in normal situation.(see attached diagram)
I have three E1s between 7609-1 to the 7609-PE, because of the hardware limitation I couldn't bundle them with PPP Multilink. So I used IP Unnumbered on the both side of each E1. So the configuration is like below:
description TO: 7609-PE
ip unnumbered Loopback2
ip ospf network point-to-point
ip ospf hello-interval 1
logging event link-status
Basicly I have one VPN on the 7609-PE, to connect this VPN to global routing table I have configured MPLS route leaking, the configuration is :
ip vrf OMU
route-target export 65500:100
route-target import 65500:100
*** VRF configuration ***
ip vrf forwarding OMU
ip address 10.131.0.105 255.255.255.255
*** To point static route inside VPN ***
ip route vrf OMU 0.0.0.0 0.0.0.0 10.131.0.6 global
*** this is default route from inside VPN to global routing table and the 10.131.0.6 is the IP Address of neighbor router- 7609-2 ***
ip route 10.131.89.0 255.255.255.224 Loopback5 10.131.80.3
*** 10.131.89.0 is direcly connected to 7609-PE under VPN OMU and loopback is under VRF OMU and the 10.131.80.3 is the BGP address of 7609-PE ***
The IGP is simple OSPF. but under OSPF there are some commands that related to traffic engineering.
On the 2800 to 7609-1 and 7609-2 there is a OSPF.
My CEF load-sharing algorithm is universal.
I'm able to ping evey clinets inside VPN from outside and able to ping all the network from inside of VPN. It means that the configuration is okey!.
My problem is if I ftp from a client that connected to 2800 to a client which is connected to 7609-PE and ping from same clinet , firts FTP is too slow and ICMP packets starting to lost !!!!
I would be grateful if you could help me in this regard. It's drive me crazy!!!!!!!
