eBGP Recommended Configuration template

Here is a peer-group recommended configuration template  for eBGP peers:

neighbor ebgp-peer peer-group
neighbor x.x.x.x description <short_description>
neighbor x.x.x.x update-source <peer_source_interface>
neighbor x.x.x.x soft-reconfiguration inbound
neighbor x.x.x.x version 4
neighbor x.x.x.x password <password>
neighbor x.x.x.x ebgp-multihop <x>
neighbor x.x.x.x remove-private-as all replace-as

the last command is valid only for IOS 15.x and above while 12.x can be configured with remove-private-as only.
