Regarding ur 3rd question ..
2001:141:1:12
2001:141:1:25
12 in hex is 010010 in bia
25 in hex is 100101 in bia
Therefore 2001:141:1::0 / 58
16*3 + 10 = 58
Regarding your second question ..( although ur question is not clear
to me what u intended to ask ).... i prefer putting ipv6 map to link
local of far end ..
But if you wanna be 100 % sure ( as no marks is deducted for xtra
config ) .. put 2 frame-relay map statements .. 1 for far end link
local address and other for far end actual IPV6 adderss.
HTH
