Hey-
Here's my dilema. I have 5 remote offices with a VPN to my corporate site. I
have internet connection from each site with ISP ABC (no reason to flame so
early). I need to add provider XYZ for redundancy. I need to use BGP for
this (because my VPN appliances only support IPSEC and no L2TP or GRE type
tunnels). My remote offices are pretty small though, about 30 users each. Of
course provider XYZ does not want to give me a full class C when I will be
using 1 or 2 addressses. So here I am stuck between $%&*@ hardware and an
ISP that won't/can't budge. The only thing I can think of is (quoting
rfc2050),
Organizations will be assigned address space based on immediate utilization
plus 1 year projected utilization. A prefix longer than
/24 may be issued if deemed appropriate. Organizations with less
than 128 hosts will not be issued an IP address directly from the
IRs. Organizations may be issued a prefix longer than /24 if the
organization can provide documentation from a registry recognized ISP
indicating the ISP will accept the long prefix for injection into the
global routing system.
They way I read this is that I can have a class C subnet advertised to my
corporate location (the "global route") and have my corporate internal
routers route to my remote offices. Is this correct? Is this my only
solution? This would seem like massive overhead on my corporate routers, but
if it's my only choice.....
