Hi Folks,
Need some kind advices from network experts, have tried the IE forum, but no replies.
Q1. Task 6.1 : IPv6 "eui-64"
When configuring IPv6 addresses on the interfaces, when do i need to include IPv6 host address "eui-64"?
2001:192:10:X::/64 eui-64
In R1, "eui-64" is used on the F0/0 interface. But not on R2's F0/0
and R5's E0/1. Is "eui-64" needed only when I need to carry out a
static frame-relay map statement?
Q2. Task 6.2 : Frame-Relay map statement on R2
Instead of using 2 x Frame-Relay map statements, one for the IPv6
/64 Network and one for the Link Local /64Host, can i just use 1 x
Frame-Relay map statement for an /128 IPv6 Network + Host
instead
frame-relay map ipv6 FE80::204:27FF:FEB5:2F60 201
frame-relay map ipv6 2001:141:1:12::1 201 broadcast
into
frame-relay map ipv6 2001:141:1:12:204:27FF:FEB5:2F60 201 broadcast
Q3. Task 6.3 : Summarize IPv6 address
Is the summarized mask supposed to be /59 instead of /58?
2 characters = 1 byte = 8 bits
2001:141:1:12 = 2001 (16bits) : 0141 (16bits) : 0001 (16bits) : 0012 (00000000 0000 1100)
2001:141:1:25 = 2001 (16bits) : 0141 (16bits) : 0001 (16bits) : 0025 (00000000 0001 1001)
Summarised Masks = 16 + 16 + 16 + 11 = 59 bits? (From Left to Right)
Thanks for any kind replies.
Much appreciated.
Cheers
Nit
