H3C S7500E Series Ethernet Switches Chapter 3 Tunneling Configuration
3-16
To do… Use the command… Remarks
Set an ISATAP tunnel
tunnel-protocol
ipv6-ipv4 isatap
Required
By default, the
tunnel mode is
manual. The same
tunnel type should
be configured at
both ends of the
tunnel. Otherwise,
packet delivery will
fail.
Configure a source address or
interface for the tunnel
source { ip-address |
interface-type
interface-number }
Required
By default, no
source address or
interface is
configured for the
tunnel.
Reference a link aggregation
group
aggregation-group
aggregation-group-id
Required
By default, no link
aggregation group
ID is referenced.
Caution:
z When you create a tunnel interface on a distributed device, the slot of the tunnel
interface should be that of the source port, namely, the port sending packets. In this
way, the forwarding efficiency can be improved.
z If the addresses of the tunnel interfaces at the two ends of a tunnel are not in the
same network segment, a forwarding route through the tunnel to the peer must be
configured so that the encapsulated packet can be forwarded normally. You can
configure static or dynamic routes at both ends of the tunnel.
z The automatic tunnel interfaces encapsulated with the same protocol cannot share
the same source IP address.
z Automatic tunnels do not support dynamic routing.
z When you configure a static route, you need to configure a route to the destination
address (the destination IP address of the packet, instead of the IPv4 address of the
tunnel destination) and set the next-hop to the tunnel interface number or network
address at the local end of the tunnel. Such a route must be configured at both ends
of the tunnel.
z Before referencing a link aggregation group on the tunnel interface to receive and
send packets, make sure that the aggregation group has been configured.
Otherwise, the tunnel interface will not be up to communicate.
