BGP Failover Traffic Flow issue

TBS1182
Level 1
Level 1

Hello all, I currently have an issue with my BGP failover configuration.

 

Current setup I have 2 Different ISPs going to 2 Different buildings. One public address space given /24

 

BGP fail over is configured through inside as no Point to Point connection exists yet. GRE tunnel has been created from the inside. WAN router connects to Firewall Outside that has a No Nat for WAN loop back. This then traverses through the inside core of building one to building to and out the Firewall to WAN router on Building 2.

 

Currently when BGP fails over, the traffic goes through building 1 to WAN 1 and sees the ISP down then sends traffic to the other side of tunnel to WAN 2. But seems like that traffic is Degraded and speeds are very low. Is this because it is going through the GRE tunnel at this point would it just make sense to create an IP SLA and action script to have everything route to Second building and out.

 

I did notice the Tunnels showing bandwidth 100Kbits.

Hello,

 

post a schematic drawing of what your setup looks like, in addition to the relevant configurations...
