The value to be advertised to the remote peer
as the Endpoint Discriminator to be used to
identify this Multilink PPP bundle.
After the remote peer has received this value,
it should include this value during LCP
negotiation of any new links intended to join
this Multilink PPP bundle.
The first byte in the string identifies the Class
of the Endpoint Discriminator. The remaining
bytes in the string contain the actual Endpoint
Discriminator value.
If the value of this variable is 0 then the
local peer will use the MAC address of the local
box as the value to advertise as the local
Endpoint Discriminator.
After the link comes up, the status variable
mpBundleStatusLocalEndptDiscr will reflect this
Endpoint Discriminator value which has been
sent to the peer (i.e. this value is not
negotiated with the peer, the peer must accept
whatever Endpoint Discriminator we send to them).
