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

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,
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.

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

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.
