I have this situation now:
ROUTER R1 BGP peering toward ISP1
ROUTER R2 BGP peering toward ISP2
is there a way to manage that both
ROUTER R1 have BGP to ISP1 and ISP2
ROUTER R2 have BGP to ISP1 and ISP2
but not to change peer address from ISP perspective( ISP1 have still only one BGP peer toward me, and simmilar for ISP2)?
(i.e.I know HSRP will not work, but something simmilar to that)
Or the only way is to have 4 BGP peerings: R1-ISP1, R1-ISP2, R2-ISP1, R2-ISP2?
