Documentation errata

An error with the BGP Configuration Guide has been corrected in this release.

BGP configuration guide

In versions earlier and including Version 17.2.0 of the BGP Configuration Guide, the guide indicated support for multiple instances of BGP per AS through the use of the multiple-instance command. This information is incorrect, as Vyatta NOS supports only one BGP instance per AS.
