202 IP Addressing
• IPv6 Hop Limit (for R1-2210) —Enter the maximum number of
intermediate routers on its way to the final destination to which a packet
can pass. Each time a packet is forwarded to another router, the hop limit
is reduced. When the hop limit becomes zero, the packet is discarded.
This prevents packets from being transferred endlessly.
•
IPv6 Link Local Default Zone Interface (for R1-2210) — Select an
interface to egress a link local packet without a specified interface or with
the default zone 0.
Defining IPv6 Global Parameters Using CLI Commands
The following table summarizes the CLI commands for defining IPv6 global
parameters:

CLI Command Description
ipv6 routing (For R1-2210) Enables IPv6 routing
ipv6 icmp error-interval
milliseconds [bucketsize]
no ipv6 icmp error-interval
Configures the interval and bucket size
for IPv6 ICMP error messages
Use the no form to return to the default
values.
ipv6 hop-limit value
no ipv6 hop-limit
(For R1-2210)Configures the maximum
number of hops used in all IPv6 packets
that are originated by the router.
Use the no form to return to the default
value.
ipv6 link-local default zone
interface-id
no ipv6 link-local default
zone
(For R1-2210)Configures an interface to
egress a link local packet without a
specified interface or with the default
zone 0.
Use the no form of this command to
return the default link local interface to
the default value.
