That was my proposal, since getting a pathattr table that nicely handles IP and non-IP NLRI is ... confusing. It also can result in less than ideal behavior when walking the whole MIB on a device that has hundreds of thousands of prefixes. >An example: I currently use both IP-FORWARD-MIB and >BGP4-MIB::bgp4PathAttrBest in SNMP scripts by parsing the config files >(interface-related routing protocol config to be exact) and checking >them against operational policy (e.g., certain kinds of interface >addresses must be in OSPF; others must not be in OSPF; some others >must be in BGP; static routes must be in BGP; etc.). Interesting. I was looking it from the point of view of not knowing exactly what prefix you were looking for (e.g., "show ip bgp 12.106.35.1" without knowing that it's in a /22). The obvious thing to do is to grab the whole table (probably inadvisable); there are more subtle ways but none are very efficient.
