How to Access and Use Quagga Shell using Avi CLI
Quagga is a network routing software suite providing implementations of various routing protocols. Avi Vantage uses Quagga for BGP based scaling of virtual services. For more information on BGP scaling on Avi Vantage, refer BGP Support for Scaling Virtual Services.
To know more about Quagga, refer Quagga Software article.
shell is used to check BGP configuration and status of BGP peer.
In this example, all the commands are executed from the default namespace on an Avi SE hosting a virtual service enabled for BGP.
To list the namespaces available, use the command
To switch to the desired datapath namespace, use the following command.
admin@AVI-SE1:ip netns exec namespace name bash
Changes in Avi Vantage Release 17.2.8
For Avi Vantage release 17.2.8 and later versions, use the
netcat localhost bgpd command instead of the
telnet localhost bgpd command to get access to the Quagga shell.
admin@AVI-SE1: netcat localhost bgpd Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Hello, this is Quagga (version 0.99.24.1).
Note: Password is avi123
If the authentication is successful, the following output is observed.
Configuration and Troubleshooting Commands
Use the command show run to check running configuration
Quagga-bgp> en Quagga-bgp# show run Current configuration: ! password avi123 log file /var/lib/avi/log/bgp/0_bgpd.log ! router bgp 65000 bgp router-id 126.96.36.199 network 10.140.99.153/32 neighbor 10.140.60.155 remote-as 3 neighbor 10.140.60.155 password avi123 neighbor 10.140.60.155 advertisement-interval 5 neighbor 10.140.60.155 timers 60 180 neighbor 10.140.60.155 timers connect 10 neighbor 10.140.60.155 distribute-list 2 out neighbor 10.140.99.157 remote-as 2 neighbor 10.140.99.157 password avi123 neighbor 10.140.99.157 advertisement-interval 5 neighbor 10.140.99.157 timers 60 180 neighbor 10.140.99.157 timers connect 10 neighbor 10.140.99.157 distribute-list 1 out ! access-list 1 permit 10.140.99.153 ! line vty ! end
Use the command show bgp neighbors to check bgp peering status.
