IPv6 Extended ACLs Chapter 24 Configuring IP Version 6 Create and Apply IPv6 ACL: Examples The following example configures two IPv6 ACLs named OUTBOUND and INBOUND and applies both ACLs to outbound and inbound traffic on Ethernet interface 0. The first and second permit entries in the OUTBOUND list permit all TCP and User Datagram Protocol (UDP) packets from network 2001:0DB8:0300:0201::/32 to exit out of Ethernet interface 0. The entries also configure the temporary IPv6 reflexive ACL named REFLECTOUT to filter returning (incoming) TCP and UDP packets on Ethernet interface 0. The first deny entry in the OUTBOUND list keeps all packets from the network fec0:0:0:0201::/64 (packets that have the site-local prefix fec0:0:0:0201 as the first 64 bits of their source IPv6 address) from exiting out of Ethernet interface 0. The evaluate command in the INBOUND list applies the temporary IPv6 reflexive ACL named REFLECTOUT to inbound TCP and UDP packets on Ethernet interface 0. When outgoing TCP or UDP packets are permitted on Ethernet interface 0 by the OUTBOUND list, the INBOUND list uses the REFLECTOUT list to match (evaluate) the returning (incoming) TCP and UDP packets. ipv6 access-list OUTBOUND permit tcp 2001:0DB8:0300:0201::/32 any reflect REFLECTOUT permit udp 2001:0DB8:0300:0201::/32 any reflect REFLECTOUT deny fec0:0:0:0201::/64 any ipv6 access-list INBOUND evaluate REFLECTOUT interface ethernet 0 ipv6 traffic-filter OUTBOUND out ipv6 traffic-filter INBOUND in Note Given that a permit any any statement is not included as the last entry in the OUTBOUND or INBOUND ACL, only TCP and UDP packets matching the configured permit entries in the ACL and ICMP packets matching the implicit permit conditions in the ACL are permitted out of and in to Ethernet interface 0 (the implicit deny all condition at the end of the ACL denies all other packet types on the interface). The following example configures HTTP access to be restricted to certain hours during the day, and to log any activity outside of the permitted hours. time-range lunchtime periodic weekdays 12:00 to 13:00 ipv6 access-list OUTBOUND permit tcp any any eq www time-range lunchtime deny tcp any any eq www log-input permit tcp 2001:0DB8::/32 any permit udp 2001:0DB8::/32 any 24-8 Cisco 10000 Series Router Software Configuration Guide OL-2226-23
