Multi Homed BGP routing with redundancy

[kartik.shah1]

Hi,

We have 2 ISP - one with 250 Mbps & other 75 Mbps.

We have 192.168.10.0/24, 192.168.11.0/24, 192.168.12.0/24,192.168.13.0/24 &192.168.14.0/24 Network Range.

We have our own AS number. 

I want traffic of 192.168.10.0/24 & 192.168.11.0/24 route to ISP A (75 Mbps) & traffic of 192.168.12.0/24, 192.168.13.0/24 & 192.168.14.0/24 should route from ISP B (250 Mbps). 

If ISP A fails, traffic should automatically routed to ISP B & when ISP A comes back, it should be routed back from ISP A.

I am planning to configure Multiple HSRP along with BGP.

I have attached N/w topology.

Kindly Provide support.

Topology looks good.

You can do in this way

Vlan 10 192.168.10.0/24  Active on Router A and standby on B

Vlan 20 192.168.11.0/24 Active on Router A and standby on B

and advertised 10 192.168.10.0/24 and 10 192.168.11.0/24 from both router but from router B with AS prepend

Similarly 

Vlan 30 192.168.12.0/24  Active on Router B and standby on A

Vlan 40 192.168.13.0/24  Active on Router B and standby on A

Vlan 50 192.168.14.0/24  Active on Router B and standby on A

and advertised 10 192.168.12.0/24, 10 192.168.13.0/24 and 10 192.168.14.0/24 from both router but from router A with AS prepend

Hello,

dual BGP with AS-Prepend - HSRP would work in this scenario:
