Re: BGP Route-Map Incoming Updates

what docuement was it?

i have seen that alot of old documents for older IOS versions keep getting
quoted alot, and then like you did when you labbed it you see that it is not
the case, at least in *that* version of IOS...

check this quote out:

"In Cisco IOS. Software releases earlier than Cisco IOS Software Release
11.2, when you use route maps to filter BGP updates rather than redistribute
between protocols, you *cannot* filter on the inbound when you use a
*match*command on the IP address. A filter on the outbound is
acceptable. Cisco IOS
Software Release 11.2 and later releases do not have this restriction."
