Clearing IPv6 Routes
To clear routes from the IPv6 routing table, use the following command.
• Clear (refresh) all or a specic route from the IPv6 routing table.
EXEC mode
clear ipv6 route {* | ipv6 address prefix-length}
• *: all routes.
• ipv6 address: the format is x:x:x:x::x.
• mask: the prex length is from 0 to 128.
NOTE: IPv6 addresses are normally written as eight groups of four hexadecimal digits, where each group is separated by a
colon (:). Omitting zeros is accepted as described in Addressing.
Disabling ND Entry Timeout
When a peer system warmboots or performs an ISSU, the ND entries in the local system may time out resulting in trac loss. You can
congure the system to keep the learnt neighbor discovery entries stateless so that the ND entries do not time out. To congure the
system to keep the learnt neighbor discovery entries stateless, follow these steps:
• Disable the ND timer:
INTERFACE
ipv6 nd disable-reachable-timer
• To reenable the ND timer, use the no form of the command:
INTERFACE
no ipv6 nd disable-reachable-timer
The following example shows how to disable the ND timer.

Secure Shell (SSH) Over an IPv6 Transport
Dell Networking OS supports IPv6 secure shell (SSH).
The Dell Networking OS supports both inbound and outbound SSH sessions using IPv6 addressing. Inbound SSH supports accessing the
system through the management interface as well as through a physical Layer 3 interface.
For SSH conguration details, refer to the Security chapter in the Dell Networking OS Command Line Interface Reference Guide.
