Understanding IPv4 uRPF on Junos DPC/MPC

uRPF allows anti-spoofing embedded at forwarding plane level. Junos provides this feature for many years with several modes and options: Loose or Strict mode Active or Feasible paths uRPF data base Discard or not supported in the uRPF data base I carried...

Need more capacity: MPC4e cards are there!

Recently, we received in LAB 2 new MPC cards: - The MPC4e Combo card: 2x100GE + 8x10GE ports (MPC4E 3D 2CGE+8XGE) - The MPC4e 32x10GE ports (MPC4E 3D 32XGE) These 2 new cards need at least the Junos 12.3 and can be used on both dense chassis: MX960 and...

Junos and BGP FlowSpec

Introduction Recently I carried out tests in labs to evaluate the FlowSpec implementation on MX960 router with TRIO MPC cards. I used a 12.3 Junos release. Those tests have covered: - IPv4 blackholing traffic feature - IPv4 rate-limiting traffic feature...

Playing with event-scripts

Last week, I worked on 2 small projects in 11.4 Junos. I should: - Find a way to automatically disable a physical link when LACP "flapped" too many times during a given time. - Find a way to automatically disable a physical link when too many CRC errors...

TRIO Card: packet capture with pfe commands

During a complex case on Juniper platform, I looked for a tip to capture transit traffic on a MX960 with Trio cards. Indeed, I suspected a Junos box to rewrite transit mpls traffic with an unexpected exp value. As I love carry out reverse engineering,...
