Hello everyone, I am trying to build out a lab in gns3 and once i figure it I will be able to put it into production but essentially what I am trying to accomplish is what is illustrated on this link :
https://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/13768-hsrp-bgp.html#diag
I have 2 circuits, WOW and ATT.
WOW is a 300/300 , ATT is 50/50
I have a /24 block from ARIN and I subnetted them down to 1x25 and 2x26
My current environment is just 1 cisco 2951 that connect to both ISP’s.
My new environment I want setup like the diagram in the link below where its redundant with 2 Cisco ISR 4351’s
My issue is i am not able to ping past the direct connected routes. I have it setup in my live environment where I only get the default route from my carriers.
From R1 I believe I should be able to route out R2 to reach 172.16.0.10 with the setup and vice versa but I am not, as well as im not sure the advertisement are working as they should either.
Does anyone see anything blatantly wrong with the configs below?
Any help is appreciated thank you
