I am multi-holmed to 2 ISP's and have a router connected to each. Each
router peers with it's respective ISP (EBGP)and the 2 peer with each
other (IBGP). It was the desire of this entity to "not waste the
redundant bandwidth", so address space is announced to both ISP's with no
prepend. This has the effect of some degree of "load sharing"; but the
routers are 3640's with all the memory that will fit in them and memory
utilization is over 90%. These are my solutions, does anyone think I
am/am not on the right track?
1. Do nothing. 90% memory utilization is fine.
2. Stop doing soft inbound reconfiguration thereby eliminating that extra
"unfiltered" table in memory.
3. Begin getting "partial routes" from each ISP. His customers and his
customers customers (or something like that)
4. Pick one Primary for INGRESS and EGRESS traffic and prefer the default
from him, and only use the secondary in case I no longer receive the
primaries default.
