MC-LAG lab – advanced IRB functionality

For simplified Layer 3 gateway services, where Layer 3 routing protocols are not run on the MC-LAG peers, you simply configure the same Layer 3 gateway IP address on both MC-LAG peers and enable IRB MAC address synchronization. This IP address is used as the default gateway for the MC-LAG servers or hosts. For more advanced Layer 3 gateway services, where Layer 3 routing protocols and Layer 3 multicast operations are required on the MC-LAG peers, you configure unique IRB…

My topology for MC-LAG practice: I already configured IP fabric between vQFX and vMX nodes using EBGP (to save space, I show the configuration for only one device – the rest are configured the same way): alex@vMX1> show configuration protocols bgp group underlay type external; export direct; local-as 65001; multipath multiple-as; neighbor 192.168.0.1 {     ###vQFX1     peer-as 65011; } neighbor 192.168.0.3 {     ###vQFX2     peer-as 65022; } alex@vMX1> show configuration policy-options policy-statement direct term…

If you look for a comprehensive explanation of MC-LAG technology – Juniper MX Series book is the best choice. For all configuration details refer to MC-LAG Feature Guide. MC-LAG configuration can be broken up into four important pieces: Inter Chassis Control Protocol (ICCP), Inter Chassis Link (ICL), MC-LAG interface and IRB interface. So let’s start with ICCP: user@switch2 > show configuration protocols iccp local-ip-addr 10.2.2.2; peer 10.1.1.1 {     session-establishment-hold-time 50;     redundancy-group-id-list 1;     backup-liveness-detection {  …

JNCIE-DC Exam Objectives and useful links

Comments 0 Comment

In this post I tried to collect all useful links to technical documentation that I plan to use during my study for JNCIE-DC lab attempt. This materials will be used primarily for repetition and more focused, deep-dive study of lab topics – should be used only after studying Juniper DC base materials from previous post. So, the complete JNCIE-DC exam blueprint: Management On-box Scripts                               –>…
