IPv6 ACLs

• Optional internet-layer information is encoded in separate headers that may be placed
between the IPv6 header and the upper-layer header in a packet. There are a small number of
such extension headers, each identified by a distinct Next Header value. IPv6 supports the
values defined for the IPv4 Protocol field in RFC 1700, including these commonly used
headers:
0 : Hop-by-Hop Options (RFC 2460)
6 : TCP Upper-layer Header (RFC 1700)
17 : UDP Upper-layer Header (RFC 1700)
43 : Routing (RFC 2460)
44 : Fragment (RFC 2460)
51 : Authentication (RFC 2402)
50 : Encapsulating Security Payload (RFC 2406)
60 : Destination Options (RFC 2460)
Example
This example accepts any incoming packets if the destination address is 2009:DB9:2229::79/8.
Console(config-ext-ipv6-acl)#permit 2009:DB9:2229::79/8
Console(config-ext-ipv6-acl)#
This allows packets to any destination address when the DSCP value is 5.
Console(config-ext-ipv6-acl)#permit any dscp 5
Console(config-ext-ipv6-acl)#
This allows any packets sent to the destination 2009:DB9:2229::79/48 when the next header is
43.
Console(config-ext-ipv6-acl)#permit 2009:DB9:2229::79/48 next-header 43
Console(config-ext-ipv6-acl)#
