• Tunneling, page 63-7
IPv6 Addressing and Basic Connectivity
The switch supports only IPv6 unicast addresses. It does not support site-local unicast addresses or
multicast addresses.
The IPv6 128-bit addresses are represented as a series of eight 16-bit hexadecimal fields separated by
colons in the format: n:n:n:n:n:n:n:n. it is an example of an IPv6 address:
2031:0000:130F:0000:0000:09C0:080F:130B
The leading zeros in each field are optional, implementation is easier without them. it is the same address
without leading zeros:
2031:0:130F:0:0:9C0:80F:130B
You can also use two colons (::) to represent successive hexadecimal fields of zeros, but you can use this
short version only once in each address:
2031:0:130F::09C0:080F:130B
The switch supports the following features:
• IPv6 address types: Anycast
• IPv6 default router preferences
• IPv6 MTU path discovery
• Neighbor discovery duplicate address detection
• Cisco Discovery Protocol — IPv6 address family support for neighbor information
• ICMPv6 redirect
• ICMP rate limiting
• DNS lookups over an IPv6 transport
• uRPF
• ICMPv6
