Hi,
I had the
ip prefix-list RIP_UPDATE seq 16 permit 0.0.0.0/0 le 32 statement on the
router. But this only helps in sending other networks other than
163.1.57.0/24 to R2. I didnt type it as my main concern was not to send the
163.1.57.0/24. Now without the paermit any statement in the prefix-list, the
default will be to deny everything. But that also does not block the network
163.1.57.0/24 from being send to R2.
It works with offset-list perfectly. But wondering why not with
distribute-list.
regards
shamin
