But but... that does not work.
I tested it, and Brian confirmed that amprgw can not route packets out
to the Internet to the BGP 44/8 sites, unless those sites are also
reachable via an IPIP mesh. The technical reason is that the first
upstream router between amprgw and the Internet has a static 44/8
route towards amprgw, and does not have the full Internet BGP table
which would contain more specific routes to the BGP-only sites.
The BGP-enabled sites currently need to be present also in the IPIP
table, and have (at least) an IPIP decapsulation gateway, so that
other regular gateways can transmit packets to them. amprgw currently
cannot act as a relay.
Yes, actually I know but I thought the routing loop at UCSD would be
temporary. OTOH those BGP-but-no-IPIP-guys are breaking the AMPRnet
and MUST fix their installation!
Also, it's more optimal to transmit the packets
directly using a
tunnel instead of trying to route via amprgw, even if it worked.
True.
