SNMP OID for Juniper QFX

I once wrote a Zabbix template for QFX5100 and will show some of the main SNMP OIDs that I used:

Configuring Juniper QFX5100

For example, I will configure the Juniper QFX5100-24Q-AFO switch.

Configuring Juniper MX and ABillS

For example, I will configure the Juniper MX204 to work with the ABillS billing system.

Juniper. Configuring RPF in Dynamic Profiles

For example, I will configure unicast RPF (reverse-path forwarding) on Juniper MX204.
RPF allows you to reduce the impact of DOS-type attacks on IPv4 and IPv6 interfaces.

Configuring iBGP on Juniper MX

For example, I will configure Internal BGP on Juniper MX204. Since there are servers with Accel-ppp (ipoe) in the network and you need to balance users between these servers and Juniper, iBGP will transfer user routes with /32 mask from all devices to the main router/routers. iBGP is also needed when there are several links to Uplink providers that are connected to different routers, then you need to configure iBGP between these routers.

Configuring OSPF on Juniper MX

For example, I will configure OSPF on Juniper MX204.

Juniper. Solution of failing auto-image upgrade

I was setting up a Juniper QFX5100 once and noticed persistent messages:

Configuring LAG on Juniper QFX5100

For example, I will configure the LAG on the Juniper QFX5100, by which I will connect the Juniper MX204.

The “monitor traffic” command allows you to view the packets or their headers that pass through the routing module, which is very useful for diagnosing various problems.
