Quagga is a network routing software suite providing implementations of various routing protocols. Avi Load Balancer uses Quagga for BGP-based scaling of virtual services.
To know more about Quagga, see Quagga Software guide.
Instructions
Quagga 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 Avi Load Balancer SE hosting a virtual service enabled for BGP. To list the namespaces available, use the command ip netns. To switch to the desired datapath namespace, use the following command.
admin@AVI-SE1:ip netns exec namespace name bash
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).
If the authentication is successful, the following output is observed:
Quagga-bgp>
Configuration and Troubleshooting Commands
Use the command show run to check running configuration:
Quagga-bgp> en Quagga-bgp# show run Current configuration: ! password <password> log file /var/lib/avi/log/bgp/0_bgpd.log ! router bgp 65000 bgp router-id 1.2.87.205 network 10.140.99.153/32 neighbor 10.140.60.155 remote-as 3 neighbor 10.140.60.155 password <password> 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 <password> 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:
10-140-4-220# *show bgp neighbors*
