Huawei S1720 Series Configuration Guide

l Valid TTL range of packets between switches
Procedure
Step 1 Configure VLANs that interfaces belong to.
<Quidway> system-view
[Quidway] sysname SwitchA
[SwitchA] vlan batch 10 20
[SwitchA] interface xgigabitethernet 0/0/1
[SwitchA-XGigabitEthernet0/0/1] port hybrid pvid vlan 10
[SwitchA-XGigabitEthernet0/0/1] port hybrid untagged vlan 10
[SwitchA-XGigabitEthernet0/0/1] quit
[SwitchA] interface xgigabitethernet 0/0/2
[SwitchA-XGigabitEthernet0/0/2] port hybrid pvid vlan 20
[SwitchA-XGigabitEthernet0/0/2] port hybrid untagged vlan 20
[SwitchA-XGigabitEthernet0/0/2] quit
The configurations of SwitchB, SwitchC, SwitchD, SwitchE, and SwitchF are similar to the
configuration of SwitchA, and are not mentioned here.
Step 2 Assign an IP address to each VLANIF interface.
[SwitchA] interface vlanif 10
[SwitchA-Vlanif10] ip address 192.168.0.1 24
[SwitchA-Vlanif10] quit
[SwitchA] interface vlanif 20
[SwitchA-Vlanif20] ip address 192.168.1.1 24
[SwitchA-Vlanif20] quit
The configurations of SwitchB, SwitchC, SwitchD, SwitchE, and SwitchF are similar to the
configuration of SwitchA, and are not mentioned here.
Step 3 Configure basic OSPF functions. The configuration details see Example for Configuring Basic
OSPF Functions.
Step 4 Configure OSPF GTSM.
# Configure the valid TTL range of packets from Switch C to other switches as [252, 255].
[SwitchC] ospf valid-ttl-hops 4
# Configure the valid TTL range of packets from Switch A to Switch C as [255, 255].
[SwitchA] ospf valid-ttl-hops 1
# Configure the valid TTL range of packets from Switch B to Switch C as [254, 255].
[SwitchB] ospf valid-ttl-hops 2
# Configure the valid TTL range of packets from Switch D to Switch C as [253, 255].
[SwitchD] ospf valid-ttl-hops 3
# Configure the valid TTL range of packets from Switch E to Switch C as [255, 255].
[SwitchE] ospf valid-ttl-hops 1
# Configure the valid TTL range of packets from Switch F to Switch C as [252, 255].
[SwitchF] ospf valid-ttl-hops 4
Step 5 Verify the configuration.
# Check whether OSPF neighbors between switches are established normally. Take Switch A
as an example. You can view the status of the neighbor relationship is Full, that is, neighbors
are established normally.
