Comparing NCLU and vtysh Commands

Using NCLU is the recommended way to configure routing in Cumulus Linux; however, you can use the vtysh modal CLI.

The following table shows the FRRouting commands and the equivalent Cumulus Linux NCLU commands.

Action	NCLU Commands	FRRouting Commands
Display the routing table	cumulus@switch:~$ net show route	switch# show ip route
Create a new neighbor	cumulus@switch:~$ net add bgp autonomous-system 65002 cumulus@switch:~$ net add bgp neighbor 14.0.0.22	switch(config)# router bgp 65002 switch(config-router)# neighbor 14.0.0.22
Redistribute routing information from static route entries into RIP tables	cumulus@switch:~$ net add bgp redistribute static	switch(config)# router bgp 65002 switch(config-router)# redistribute static
Define a static route	cumulus@switch:~$ net add routing route 155.1.2.20/24 bridge 45	switch(config)# ip route 155.1.2.20/24 bridge 45
Configure an IPv6 address	cumulus@switch:~$ net add interface swp3 ipv6 address 3002:2123:1234:1abc::21/64	switch(config)# int swp3 switch(config-if)# ipv6 address 3002:2123:1234:1abc::21/64
Enable topology checking (PTM)	cumulus@switch:~$ net add routing ptm-enable	switch(config)# ptm-enable
Configure MTU in IPv6 network discovery for an interface	cumulus@switch:~$ sudo cl-ra interface swp3 set mtu 9000	switch(config)# int swp3 switch(config-if)# ipv6 nd mtu 9000
Set the OSPF interface priority	cumulus@switch:~$ net add interface swp3 ospf6 priority 120	switch(config)# int swp3 switch(config-if)# ip ospf6 priority 120
Configure timing for OSPF SPF calculations	cumulus@switch:~$ net add ospf6 timers throttle spf 40 50 60	switch(config)# router ospf6 switch(config-ospf6)# timer throttle spf 40 50 60
Configure the OSPF Hello packet interval in number of seconds for an interface	cumulus@switch:~$ net add interface swp4 ospf6 hello-interval 60	switch(config)# int swp4 switch(config-if)# ipv6 ospf6 hello-interval 60
Display BGP information	cumulus@switch:~$ net show bgp summary	switch# show ip bgp summary
Display OSPF debugging status	cumulus@switch:~$ net show debugs	switch# show debugging ospf
Show information about the interfaces on the switch	cumulus@switch:~$ net show interface	switch# show interface To quickly check important information, such as IP address, VRF, and operational status, in easy to read tabular format: switch# show interface brief
