wfBgpVersion
1.3.6.1.4.1.18.3.5.3.2.5.1.1.7
Vector of supported BGP protocol version numbers.
Each peer negotiates the version from this vector.
Versions are identified via the string of bits
contained within this attribute. The first octet
contains bits 0 to 7, the second octet contains
bits 8 to 15, and so on, with the most significant
bit referring to the lowest bit number in the octet
(e.g., the MSB of the first octet refers to bit 0).
If a bit, i, is present and set, then the version (i+1)
of the BGP is supported.
