I can't believe this one isn't working, I am sure I am looking over something stupid. I needed to mux up 3x T1's between a location.
Information is as follows: (relevant bits) Location-A: Cisco 1720 ! interface Serial0 description To Location-B ip address 38.103.8.238 255.255.255.252 ! ip route 0.0.0.0 0.0.0.0 38.103.8.237 ! Location-B: Cat5500 RSM ! interface Multilink1 description T1 MultiLink PPP Bundle to Location-C ip address 192.168.98.29 255.255.255.252 ppp multilink multilink-group 1 ! interface Serial1/2:1 description To Location-A ip address 38.103.8.237 255.255.255.252 ! interface Serial1/5:1 description T1 3 of 3 (MultiLink) no ip address encapsulation ppp ppp multilink multilink-group 1 ! interface Serial1/6:1 description T1 2 of 3 (MultiLink) no ip address encapsulation ppp ppp multilink multilink-group 1 ! interface Serial1/7:1 description T1 1 of 3 (MultiLink) no ip address encapsulation ppp no fair-queue ppp multilink multilink-group 1 ! ip route 0.0.0.0 0.0.0.0 to global internet gateway! Location-C: Cisco 6509 Sup2 w/FlexWan ! interface Multilink1 description T1 Bundle to Corporate ip address 192.168.98.30 255.255.255.252 ppp multilink multilink-group 1 ! interface Serial3/0/0:0 description T1 1 of 3 no ip address encapsulation ppp no fair-queue ppp multilink multilink-group 1 ! interface Serial3/0/1:0 description T1 2 of 3 no ip address encapsulation ppp ppp multilink multilink-group 1 ! interface Serial3/0/2:0 description T1 3 of 3 no ip address encapsulation ppp ppp multilink multilink-group 1 ! ip route 0.0.0.0 0.0.0.0 192.168.98.29 ! The interfaces are up and running, the multilink bundle looks good, and if I ping or trace from A to B, or B to A life is good. If I try and go from B to C or C to B, again life is good. If I try and go from A to the internet via B, or from C via B to the internet all is good. So it looks like all is working. Where I get bit, is if I try and go from A to C, or C to A. I can not ping, and if I trace it dies on router B. So it looks like single hop is good, and if I go to another location out off of B (other networks) all is good, but if I try and cross any other internal interface on the router and cross the MLPPP link it dies. I was just going to use CEF to handle the link with per-packet load sharing with a dynamic routing protocol, but apparently the FlexWan controller doesn't support it, or it barked about an unknown command. Anyway trying to debunk this I stripped it back to the above, just static routes between A-to-B-to-C, and still it will not route. This is part of a larger network, and none of the other remote enpoints will cross that multilink line, and I can't pin down why. I am open to any suggestions, as I rarely use MLPPP, and am sure I am missing something, but damn I would think two simple hops with static routes should just go. Thanks to any that can offer assistance on debunking this one.. P.S. - Yes I know I have some routable, and some unroutable IP's, but this is all behind a firewall, and gateways out, I just haven't gotten them to pull the old public IP's out, granted that shouldn't matter for an internal (in essence) isolated network. --- Howard Leadmon _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
