Removed this config line "set protocols bgp parameters default no-ipv4-unicast"
which does not exist in the latest rolling release but this functionality is
enabled by default. And corrected few grammar mistakes
There were minimal grammatical and spelling mistakes in the files which I
corrected as documentation proof reading.
Also added information about few ipsec vpn parameters.
BGP as number is no longer represented as a tag node on "protocols bgp <asn>"
but rather is not represented as leafNode under "protocols bgp local-as <asn>"
Adding documentation on the default RFC8212 behavior for FRR, and
how in VyOS we are changing that default. Also added information
on the toggle option to enable/disable said RFC8212 functionality.
This is a documentation addition for the allow range command
within BGP, as well as the associated limit command as well.
There was a few spelling mistakes that were fixed too, but
not anything big.
