Configuration Notes Keep in mind the following issues when you are running your Cumulus VX virtual machine.

Enabling SNMP in Quagga There is no SNMP support for Quagga in Cumulus VX. Due to this circumstance, you must remove all references to smux in each of the following configuration files. If the smux entries are present in the configuration files, the daemons in the 2.5 packaged version of Quagga will not start.
  1. cd /etc/quagga
  2. grep smux *
  3. Delete all lines in the config files containing the smux keyword.
The references to smux that must be removed are:
  • In bgpd.conf, remove this line: smux peer quagga_bgpd
  • In ospf6d.conf, remove this line: smux peer quagga_ospf6d
  • In ospfd.conf, remove this line: smux peer quagga_ospfd
  • In zebra.conf, remove this line: smux peer quagga_zebra
