I have some problems in my BGP multihomed lab with HSRP to the inside network
there are two ISPs with different AS of course. Router R1 is connected to one ISPA (AS 100) and Router R2 is connected to ISPB (AS 200). The routers have an IGBP Connecttion within AS 300. The ISPs advertise some prefixes and the own AS 300 advertise also one prefix (22.214.171.124/16)
In the inside network the routers are connected to one switch with Fa3 and to the ASA firewall and HSRP with specific priorities is working.
OUTSIDE Traffic is no problem due HSRP logic. But INSIDE traffic from the simulated internet is loadbalanced over the two routers. When the INSIDE Interface of one router goes down, then the connected network to the ASA will get lost and then the BGP backhole summary route come in place and the traffic will get lost.
To solve this I think backup static routes to the neighbor (R1/R2) router for the connected network will be the best?
