Bart,
Don brought up some good points. In addition:
- non Linux-kernel routers (e.g. JNOS and TNOS) would not be able to route to you as they would need to be reprogrammed and recompiled (FYI, JNOS and TNOS is the most commonly used AMPR Network OS)
- (bad practice) packets destined for invalid 44IPs are now forwarded on to AMPRGW instead of dropped by the local GW (recall, only BGP subnets who DO NOT want to run RIP44 and IPENCAP would need this reconfiguration and only your subnet needs this exception)
