EOS Defaults

The following list of commands change the default behaviour of an EOS device to be more like a layer 3 routing device than it's default state of a layer 2 switching device:

# Default ports to be layer 3 routed ports which support sub-interfaces instead of layer 2 switched pots:
switchport default mode routed

# Disable spanning tree
spanning-tree mode none

# Enable routing protocol and VRF support
service routing protocols model multi-agent

# Enable IPv4/IPv6/MPLS
ip routing
ipv6 unicast-routing
mpls ip

# Disable management in all VRFs except management VRF (it will default to being enabled in all VRFs!)
management ssh
 vrf management
  no shutdown
  exit
 shutdown

# Set eBGP admin distance to 20, it deaults to 200, equal with iBGP:
router bgp
 distance bgp 20 200 200
