Setup Guide

interface Tunnel 2
no ip address
ipv6 address 2::1/64
tunnel destination 90.1.1.1
tunnel source 60.1.1.1
tunnel mode ipv6ip
no shutdown
The following sample conguration shows a tunnel congured in IPIP mode (IPv4 tunnel carries IPv4 and IPv6 trac):
DellEMC(conf)#interface tunnel 3
DellEMC(conf-if-tu-3)#tunnel source 5::5
DellEMC(conf-if-tu-3)#tunnel destination 8::9
DellEMC(conf-if-tu-3)#tunnel mode ipv6
DellEMC(conf-if-tu-3)#ip address 3.1.1.1/24
DellEMC(conf-if-tu-3)#ipv6 address 3::1/64
DellEMC(conf-if-tu-3)#no shutdown
DellEMC(conf-if-tu-3)#show config
!

tunnel source 5::5
tunnel mode ipv6
no shutdown
Conguring Tunnel Keepalive Settings
You can congure a tunnel keepalive target, keepalive interval, and attempts.
NOTE
: By default, the tunnel keepalive is disabled.
The following sample conguration shows how to use the tunnel keepalive command.
Conguring a Tunnel Interface
You can congure the tunnel interface using the ip unnumbered and ipv6 unnumbered commands.
To congure the tunnel interface to operate without a unique explicit IP or IPv6 address, select the interface from which the tunnel borrows
its address.
The following sample conguration shows how to use the interface tunnel conguration commands.
Conguring Tunnel Allow-Remote Decapsulation
You can congure an IPv4 or IPV6 address or prex whose tunneled packet is accepted for decapsulation.
• If you do not congure allow-remote entries, tunneled packets from any remote peer address are accepted.
• You can congure up to eight allow-remote entries on any particular multipoint receive-only tunnel.
The following sample conguration shows how to congure a tunnel allow-remote address.
DellEMC(conf)#interface tunnel 1
DellEMC(conf-if-tu-1)#ipv6 address 1abd::1/64
DellEMC(conf-if-tu-1)#ip address 1.1.1.1/24
DellEMC(conf-if-tu-1)#tunnel source 40.1.1.1
DellEMC(conf-if-tu-1)#tunnel mode ipip decapsulate-any
DellEMC(conf-if-tu-1)#tunnel allow-remote 40.1.1.2
DellEMC(conf-if-tu-1)#no shutdown
DellEMC(conf-if-tu-1)#show config
