Hi Gs,

R5 ------R1---------R2

R1 ,R2 ,R5 run frame-relay on their main serial interface.

I ran Ipv6 and Ripng on them.

I have v6 routes is each routers table

R5:

interface Serial1/0

 ipv6 address 2001:CC1E:1:125::5/64
 ipv6 address FE80::5 link-local
 ipv6 rip 1 enable
 frame-relay map ipv6 FE80::CE00:15FF:FE2C:0 501 broadcast
 frame-relay map ipv6 2001:CC1E:1:125::1 501 broadcast
 frame-relay map ipv6 2001:CC1E:1:125::2 501 broadcast

R1 :

interface Serial1/0
 ipv6 address 2001:CC1E:1:125::1/64
 ipv6 address FE80::1 link-local
 ipv6 rip 1 enable
 frame-relay map ipv6 FE80::CE01:15FF:FE2C:0 102 broadcast
 frame-relay map ipv6 FE80::CE04:15FF:FE2C:0 105 broadcast
 frame-relay map ipv6 2001:CC1E:1:125::2 102 broadcast
 frame-relay map ipv6 2001:CC1E:1:125::5 105 broadcast

R2 :

interface Serial1/0
 ipv6 address 2001:CC1E:1:125::2/64
 ipv6 address FE80::2 link-local
 ipv6 rip 1 enable
 frame-relay map ipv6 FE80::CE00:15FF:FE2C:0 201 broadcast
 frame-relay map ipv6 2001:CC1E:1:125::1 201 broadcast
 frame-relay map ipv6 2001:CC1E:1:125::5 201 broadcast

Question is : Is there any nedd to L3 to L2 link-local mapping for R2 on R5
s1/0 ??? I see this solution with L3 to L2 mapping in some workbooks.

As I said every thing is right ,I think this L3->L2 mapping will be
redundant.

any idea?

Cyrus
