no ip icmp error-interval
Use the
no
form of the command to return
burst-interval
and
burst-size
to their default values.
4.11
IP in IP Tunneling Commands
This feature provides basic Layer 3 IPv4 in IPv4 tunnelling using the encapsulation/decapsulation as defined in RFC
2003. This implementation allows the user to configure a tunnel that can be used as a next-hop in routing decisions.
When used with routes/default route, matching packets will be encapsulated and sent to the remote IP address
configured for the tunnel.
Arriving packets that come from the configured tunnel source IP will be decapsulated and the resulting packet will
undergo normal forwarding.
Tunnels can be statically provisioned. No specific security related options are implemented, i.e. tunnel packets are
simple, unauthenticated and unchecked packets.
ICMP messages are not generally generated or forwarded from within the tunnel itself. This means that for example,
when the tunnel is down, no “ICMP unreachable” is generated. It also means that PATH MTU discovery will not work
as expected. Each host sending data through the tunnel should thus use an appropriately lowered MTU.
4.11.1
interface tunnel
This command enters tunnel configuration mode. Up to 8 distinct tunnels can be configured. Each tunnel is identified
by the IP addresses of the local and remote end points of the tunnel, as well as the local tunnel IP address, which
is used to identify the tunnel as a next hop for routes.
Only a single tunnel is allowed for each combination of tunnel source and destination end points, i.e. it is not possible
to define multiple tunnels between the same end points.
4.11.2
tunnel mode
This command enabled RFC 2003 encapsulation for the specific tunnel. It can be used in tunnel mode, which is
activated through the interface tunnel <number> command.
