This is all good..... but then, it says "For failover use the following ports for the reth and tie to redundancy groups" set interfaces xe-6/0/0 gigether-options redundant-parent reth0. set interfaces xe-6/1/0 gigether-options redundant-parent reth1. set interfaces xe-18/0/0 gigether-options redundant-parent reth0

Have you configured reth-count using command, "set chassis cluster reth-count 15".. Also, if you configure and still it is not working, you add following command.. "set interfaces reth2 redundant-ether-options minimum-links 1".. However, i do suggest to share the full configuration to troubleshoot further..

set chassis cluster reth-count 10 set chassis cluster redundancy-group 3 node 0 priority 100 set chassis cluster redundancy-group 3 node 1 priority 1 set chassis cluster redundancy-group 3 preempt set chassis cluster redundancy-group 3 interface-monitor ge-0/0/2 weight 255 set chassis cluster redundancy-group 0 node 0 priority 100

Now, we'll increase the reth-count to match the number of physical interfaces on the unit set chassis cluster reth-count 8 Now change the redundancy-group to port mapping so that the reth, redundancy group and interface numbers all line up (you'll thank me later): delete redundancy-group 1 set redundancy-group 3 node 0 priority 200

May 28, 2023 · Not sure, but it looks like you are confusing reth (redundant ethernet) with ae (aggregated ethernet or port channel on Cisco). With reth interfaces these are configured as standard single ethernet ports. The pair are redundant so that one and only one is passing traffic at any time depending on the failover status of the reth group on the SRX.

Oct 29, 2024 · Third - If is not possible to use reth and irb in same time, for example for reth0.111 and irb.111 does that mean that all configuration for reth0 it should be change to IRB. I mean to delete Reth interface and add the ports from reth0 to IRB interfaces and then to add the IRB interfaces to proper security zones.

Mar 14, 2023 · Reth is short for Redundant Ethernet interface. These are used on clusters of two SRX devices as part of the failover mechanism. With Redundant ethernet a pair of ports back each other up. Only one of the two ports is active at a …

Reth interfaces are generally used as L3 interfaces. In you configuration I see that you need a L2 interface (running ethernet-switching) to be able to have multiple switches connected to same node. Please refer below KB for ethernet-switching with chassis cluster.

Now if both reths are in different zone then this might not serve will the design, because if one reth is unable to reach remote gateway (suppose this is primary link to reach remote gateway ) then lo0.x will try to reach remote gateway through second reth but it is in different zone so new session will be established, there might be little bit ...

Jun 30, 2023 · This message was posted by a user wishing to remain anonymous. Hey all, I've been labbing a concept on clustered vSRX, with back-to-back reth interfaces and using ip-monitoring to facilitate failover between the reth interfaces when a failure occurs that does not include a physical interface going down (interface monitoring).
