Hi all,

I think my doubt is a little dummy.

I made these configurations, however ipv4 works but ipv6 doesn't work and I still haven't found the reason, if someone can help me.

In attached R7 and R5.

access-list polka4
 sequence 10 permit 1 7.7.7.0 255.255.255.252 all 20.20.20.6 255.255.255.255 all
 exit
!
access-list polka6
 sequence 10 permit 1 7777:: ffff:ffff:ffff:ffff:: all 2020::6 ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff all
 exit
!

R7---R5---R1---R3

                 |        |

                 |        |

                 |        |

       R6---R2 ---R4
