Vince,
Effective today, we have ceased sending most of the explicit routes for the supernet 192.216/16 to the CIX and have requested that they be removed from the NSFNET PRDB. The single exception to this change is 192.216.61, which is multi-homed.
Assuming no problems are found with 192.216/16, we will next remove all singly-homed explicit routes in the blocks 198.31/16 and 198.92/14.
According to the MERIT PRDB, these changes will removed approximately 530 class-C network routes. According to a recent routing table dump, this will translate into approximately 210 active routing table entries. Furthermore, it should cause BARRNet to cease aggrevating the global routing table problem as the vast majority of our new subscribers are assigned network numbers from one of our CIDR blocks.
Anybody else ready to take the plunge?
Sure. Today, SURFnet ceased sending any of the explicits in the two large SURFnet CIDR blocks: - 145.0.0.0/9 - 192.87.0.0/16 Some explicits in these blocks remain since the sites using these nets are connected to another provider (but long matches take precedence so no routing problem occurs), but these are not announced by SURFnet (maybe we should try to get those numbers back one day...). This step means that around 60 networks are gone from the routing tables (okay, SURFnet has some smaller numbers than BARRnet :-), but everything helps, IMHO). SURFnet is issuing network numbers from the SURFnet CIDR blocks for customers that are new in the Internet game. SURFnet also "asks gently" from sites that already obtained address space some time ago to renumber to the SURFnet CIDR blocks. Up till now I have been effective in all case except one, since I play this game. This is really worth trying. Who's next? __ Erik-Jan.
