Static Route; Static Routing Features Supported By The S6700 - Huawei S6700 Series Configuration Manual

S6700 Series Ethernet Switches
Configuration Guide - IP Routing

1.1 Static Route

Static routes are special routes that network administrators must manually configure.
On a simple network topology, you only need to configure static routes so that the network can
run properly. Properly using static routes improves the network performance and provides the
guaranteed bandwidth for important applications.
The disadvantage of static routes is that if a fault occurs on the network or the network topology
changes, static routes cannot automatically change and must be changed manually by the
administrator.

1.2 Static Routing Features Supported by the S6700

The system supports various static route features, including IPv4 static routes, IPv6 static
routes, default routes, BFD for IPv4 static routes.
IPv4 Static Route
IPv4 static routes need to be manually configured by the administrator. IPv4 static routes are
applicable to simple IPv4 networks.
An IPv4 static route is an IPv4 default route if its destination address is 0.0.0.0 and the mask
length is 0.
If the destination address of an IPv4 packet fails to match any entry in the routing table, the
switch uses the IPv4 default route to forward the IPv4 packet.
The S6700 supports ordinary static routes .
IPv6 Static Route
Similar to IPv4 static routes, IPv6 static routes need to be manually configured by the
administrator. IPv6 static routes are applicable to simple IPv6 networks.
If the destination address of an IPv6 static route is ::/0 with the mask length being 0, this IPv6
static route is an IPv6 default route.
If the destination address of an IPv6 packet fails to match any entry in the routing table, the
switch uses the IPv6 default route to forward the IPv6 packet.
Default Route
Default routes are a special type of routes. Generally, administrators can manually configure
default routes.
Default routes are used only when packets to be forwarded fail to match any entry in the routing
table. You can run the display ip routing-table command to check whether the default route is
configured.

NOTE
The main differences between IPv6 static routes and IPv4 static routes are their destination addresses and
next-hop addresses. The next-hop address of an IPv6 static route is an IPv6 address, whereas the next-hop
address of an IPv4 static route is an IPv4 address.
