Understood! you would _still_ take default BGP routes, I was implying more
along the lines (in cisco speak):
! Tweak as necessary to get a good balance
ip route 0.0.0.0 220.127.116.11 <peer1>
ip route 18.104.22.168 22.214.171.124 <peer2>
Set up SLA tracking on the peer IPs to retract the routes if either peer goes
Either that or get more RAM on your router and go the BGP-only method.
