frame-relay cant ping from pont to point to multipoint

hi all,ive set up a frame relay lab using a fr switch for multi point  also have set up a point to point through the switch to 1 of the mp  routers(drawing of topology to be added),the pvcs work and i can ping  from first router to both multi points and from multi r1 to multi r2 and  can ping the point to point link 2 but cannot ping between p2p and  multi point

can ping from r1s0/0.102-103(191.168.123.1)191.168.123.2 s0.201 and 3(multi point) 301

and can ping from r1(191.168.12.1)s0/0.112 to r2 191.16812.2 211 s0/0.211

but cannot ping from 191.168.123.3 to 191.168.12.2

heres the show run from all 3 routers and fr switch

frame-relay cant ping from pont to point to multipoint

Hi,

1)on the FR switch, no need for any routing protocol as well as FR mappings, this is just a switch.

   But it is not configured as a FR relay switch in the output config you posted ? where is this part of the config

2) on R1: on the multipoint subnet  you must have s0.103 pointing to R3 and not s0.102 which is already pointing to R2

      if you want to use a FR switch

3) split-horizon problem symptom is the spokes see the hub routes but not the other spokes routes so on the hub which should be R1 you have to disable split-horizon for the EIGRP process with the no ip split-horizon eigrp x interface command.

Regards.

Alain.

frame-relay cant ping from pont to point to multipoint

Hi,

you surely have a problem with EIGRP split-horizon( but I just took a quick look at the configs and diagram).

Can you post output of sh ip route eigrp on all routers as well as sh ip eigrp neigh

Regards.

Re: frame-relay cant ping from pont to point to multipoint

hi cadet thanks for your reply,ok nso ill tell u wot ive done first then post the outputs,after your reply i looked in each routing tables and the route was there but as a summarised route sh i checked sh ip protocols and on all 3 routers i had not done no auto-summarisation,so added the command to all 3 router but not thr fr switch(do i need to??do i even need to enable eigrp on fr switch ??as i have)now some rout tables sh the route and some dont heres outputs

frame-relay cant ping from pont to point to multipoint

Hi,

1)on the FR switch, no need for any routing protocol as well as FR mappings, this is just a switch.

   But it is not configured as a FR relay switch in the output config you posted ? where is this part of the config

2) on R1: on the multipoint subnet  you must have s0.103 pointing to R3 and not s0.102 which is already pointing to R2

      if you want to use a FR switch

3) split-horizon problem symptom is the spokes see the hub routes but not the other spokes routes so on the hub which should be R1 you have to disable split-horizon for the EIGRP process with the no ip split-horizon eigrp x interface command.

Regards.

Alain.

hi alain when i looked on R1 the commands for split horizon was for the eigrp process  so must of missed a bit off while copying and the frame relay switch was the whole wrong sh run not sure why i posted stockholm twice lol so the fr switch has all the right config,it was no 2 as soon as i did what u said i could ping accross,thanks for your help
