  • 1.  SRX and SSR / Conductor intergration

    Posted 06-30-2022 09:02
    Hello all
    I'm looking for configuration example for integration between SRX and SSR.
    Can someone help with this?

    Thanks

    The SRX does not currently support the SVR protocol. Integration would be accomplished through standard routing protocols just as if you are connecting to any other router. Please elaborate if you need further assistance.

    Hi Dustin, 

    I saw that SVR was introduced as a feature for SRX in Junos 21.4, but the release note below doesn't mention anything about Conductor (or Mist post v6.0 release) integration. Is this on the roadmap for SRX? It would be great to be able to deploy SRXs with full Conductor based SVR and interoperability with SSRs. 

    https://www.juniper.net/documentation/us/en/software/junos/release-notes/21.4/junos-release-notes-21.4r1/topics/new-features/feature-descriptions/routing-policy-and-firewall-filters-6.html

    Cheers
    Dusty

    Hi,

    Here is a sample of working configuration between SRX and SSR using SVR (vector routing):
    SRX side
    services {
        vector-routing {
            authority-name Authority128;
            cipher-suites {
                vsrx {
                    authentication-disabled;
                    encryption-disabled;
                }
                internal {
                    authentication-disabled;
                    encryption-disabled;
                }
            }
            router vsrx-222 {
                node vsrx-222 {
                    interfaces {
                        ge-0/0/1.0;
                        ge-0/0/0.0 {
                            adjacency {
                                adj1 {

    SVR is working on both SRX and vSRX, and it should work on NFX as well using version:
    version 21.4R2.10;​


    You should see that the peering is up before the SRV interconnection will work:

    show services vector-routing peer-summary
    
    Logical-system or Tenant            Peer               adjacency                  status
    ------------------------------------------------------------------------------------------
    
    root-logical-system
                                        TA-DC-Router
                                                           adj2                       UP

    Please note that some naming must match in both sides (SRX and SSR), for example Authority name, Router name, Service name, Tenant name, Security policy name, etc.
    This example is without encryption between nodes and later will post another example with encryption and how to configure it.

    Hope it helps,
    Ivan
