Hi Team:
Hope this isn't too much of a both, but I am going through IPv6 right now
and am really trying to figure out the times when it is necessary to include
certain "options" on commands.
Configure IPv6 on the Frame Relay circuit between R1, R2, and R3 using
the network 2001:149:X:123::/64.
Thank-you very much
R1:
ipv6 unicast-routing
!
interface Serial0/0
ipv6 address 2001:149:1:123::1/64 (THE STATEMENT NETWORK IN THE QUESTION
HAS TWO COLONS AT THE END, WHICH I HAVE TAKEN TO MEAN ADDING AN EUI-64
OPTION FOR DYNAMICALLY GETTING THE HOST PORTION OF THE IPV6 ADDRESS. WHY IS
THIS THE CASE HERE. WHAT TELLS ME THAT I SHOULD USE THIS ADDRESS AS OPPOSED
TO 2001:149:X:123::/64 EUI-64?)
ipv6 address fe80::1 link-local (IS THE REASON A LINK LOCAL ADDRESS ASSIGNED
HERE BECAUSE OF A DYNAMIC ROUTING PROTOCOL THAT HAS TO BE RUN OVER THE
FRAME-RELAY CLOUD?)
frame-relay map ipv6 2001:149:1:123::2 103 broadcast WHY IS THE BROADCAST
OPTION NECESSARY HERE? IS IT BECAUSE OF DYNAMIC ROUTING PROTOCOLS THAT USE
MULTICAST ADDRESSES FOR ROUTING UPDATES? IS IT BECAUSE REAL MULTICAST NEEDS
TO BE OVER THE SERIAL LINK? WHY IN THIS CASE IS BROADCAST SUPPORT NOT
DEFINED FOR THE LINK LOCAL ADDRESS?
frame-relay map ipv6 FE80::3 103
frame-relay map ipv6 FE80::2 103 WHY IN SOME CASES IS THE ENTIRE HOST
PORTION OF THE IPV6 ADDRESS (SITE, LINK OR GLOBAL) WRITTEN OUT WHEREAS OTHER
TIMES, ONLY "2" OR "3", ETC., IS DEFINED?
frame-relay map ipv6 2001:149:1:123::3 103
R2:
ipv6 unicast-routing
!
interface Serial0/0
ipv6 address 2001:149:1:123::2/64
ipv6 address fe80::2 link-local
frame-relay map ipv6 2001:149:1:123::3 203 broadcast
frame-relay map ipv6 FE80::1 203
frame-relay map ipv6 FE80::3 203
frame-relay map ipv6 2001:149:1:123::1 203
R3:
ipv6 unicast-routing
!
interface Serial1/0
ipv6 address 2001:149:1:123::3/64
ipv6 address fe80::3 link-local
frame-relay map ipv6 FE80::2 302
frame-relay map ipv6 FE80::1 301
frame-relay map ipv6 2001:149:1:123::2 302 broadcast
frame-relay map ipv6 2001:149:1:123::1 301 broadcast
