We already have BGP implemented (ISP redundancy) at the main office building. It's got its ARIN approved ASN and a /24 prefix announced to the upstream ISPs.
My question is that if we were going to implement BGP at a branch office, do we need to apply a new AS number? Will it be a brand new setup or we can somehow use the same ASN? The branch office has its own /24 prefix and Internet connection. It talks to the main office through a L2L VPN tunnel.
If we can use the same ASN, what are the special configurations we need to be aware of? Thanks in advance.
Assuming iBGP peers need to be fully meshed and they need to be able to reach each other through either IGP or EGP network. We can implement Route-reflector or Confederation but how do we do that across public IP space WAN?
I have two routers running BGP on each side. I am sure we can do route-reflector or confederation to make iBGP working. However I am concerned about peering iBGP across multiple hops over the Internet. The hello packet is sent every 60 seconds by default. I just wanted to make sure this is the best practice and commonly deployed in the field.
I'm working on a project that includes basic router configurations. I configurated everything including: line console 0, line vty 0 15 and secret passwords. There are 3 routers in the network and every LAN is going t...
