ok, but why- after i typed in the config below - did i then see the ipv6
address in the running config, even tho i did not enter it??? it was as
though there was some sort of ipv6 negotiation/discovery process involved in
this.....
(preface/post-face: this was an IE lab. i was configuring ipv6 to peer w/
a backbone router of which i had no control over. the running config of my
router had the ipv6 mapping as though i entered it manually doing:
router bgp 100
nei 1.2.3.5 remote 100
address-fam ipv6
nei xxxx.xxxx.xxxx.xxxx:: remote 100
