Router Config

In here, we're going over the configuration needed for our Ubiquiti router.

1. SSH into the router
2. Install and configure frr

   curl -s https://deb.frrouting.org/frr/keys.asc | apt-key add -
   echo deb https://deb.frrouting.org/frr bullseye frr-stable | tee -a /etc/apt/sources.list.d/frr.list
   apt update
   apt install frr frr-pythontools -y
   
   cat > /etc/frr/frr.conf << EOF
   ! -*- bgp -*-
   !
   frr defaults traditional
   log file stdout
   !
   router bgp 65510
    bgp ebgp-requires-policy
    bgp router-id 10.0.0.1
    maximum-paths 1
    !
    ! Peer group for DNS
    neighbor DNS peer-group
    neighbor DNS remote-as 64512
    neighbor DNS activate
    neighbor DNS soft-reconfiguration inbound
    neighbor DNS timers 15 45
    neighbor DNS timers connect 15

    ! Neighbors for DNS
    neighbor 10.4.0.201 peer-group DNS
    neighbor 10.4.0.202 peer-group DNS
    neighbor 10.4.0.203 peer-group DNS
   
    address-family ipv4 unicast
     redistribute connected
     !
     neighbor DNS activate
     neighbor DNS route-map ALLOW-ALL in
     neighbor DNS route-map ALLOW-ALL out
     neighbor DNS next-hop-self
    exit-address-family
    !
   route-map ALLOW-ALL permit 10
   !
   line vty
   !
   EOF
   
   chown frr:frr /etc/frr/frr.conf

3. Enable bgpd in /etc/frr/daemons
