Hello You can use the bgp path attributes (PA's) (local preference-as-path ) or  Policy Based Routing (PBR) - Both options have differing results - but either one you choose you may also need to take into account  asymmetric routing regards the return traffic   If you use Policy Based Routing (PBR) you can specify certain internal users/subnets to be policy routed via the 2nd bgp path but here you dont really have any control on the return traffic.   Using BGP PA's  for egress traffic you can use local preference, here  you can specify on certain received routes you wish for internal users to take the 2nd path for.   Using BGP PA's for ingress traffic you can use as-path prepending  here you can specify  certain internal prefixes that you wish to be advertised with a longer as-path sequence towards the least preferred isp, The isp in turn will see these routes with a longer as-apath and so will take the shorter path back towards your rts which will be rtr2.   ...

Also the topology doesn't seem correct - You have a l3 core switch connecting to two rtrs which are then connected to an ISP server on one side and a cisco website server on a another? Can you verify if this is correct? ... View more

Hello As others have stated you need to make sure your mgt interface is up which it looks like it is for vlan 1 The default-gateway of this switch needs to be 165.122.3.x  which will be the I am guessing the ip of your root core switch. Can you ping this switch from the core switch? if yes - can you still ping this switch from the core switch sourced from another vlan interface    Looking at your port-channels, you have 4 defined but only two are up and one of those (PC3) is only partially up. This PC looks like it isn't configured correctly either, Its suggests you either manually created the PC or manually configured the physical interfaces.after the PC was created.   Why do you have lacp applied to PC3 and not PC1?   Do you have any access-lists  applied to this switch line interfaces  that would negate remote-access? Is remote access allowed on this switch? sh run | be line sh access-list ... View more
