Hi Brian,
You've made me curious. I just stood up a 44 net BGP connection (thank
you!). Wouldn't it improve the performance of the 44net traffic (not the
internet exchanged traffic) if I also setup RIP over tunnels to the tunneled
sections of the network?
Thanks,
Bill Buhler

Minimum netmask size for BGP is /24.
Correct. The operators of the networks which make up the Internet backbone
have chosen not to accept BGP advertisements that are narrower than a /24,
possibly to minimize the number of entries in the global routing table, so
if you choose DIRECT (BGP) as your subnet connection method, the portal
adjusts your netmask up to a /24 if you have chosen something smaller.
Note that to have a BGP-advertised subnet, you must have arranged with your
Network Service Provider that they will in fact supply you with a connection
based on their advertising your subnet to the Internet
backbone as being CIDR-routed. It is unusual for NSPs to do this;
many won't and others charge a significant amount for the service.
You should NOT select Direct in a portal allocation request unless you have
arranged for this service from your NSP.
In any case, your subnet will be connected to the Internet by at most ONE
method: Radio, Tunnel, or Direct, and might not be connected at all, so
select at most ONE of the connection method boxes in the allocation request.
(I have asked that these selections be changed to a pulldown list or radio
buttons so that it is impossible to select more than one; until that
happens, requests having more than one box checked are likely to be
rejected.)
