  • 1.  FBF not working on EX4600

    Posted 07-16-2023 12:51

    A few months ago, I configured FBF on a SRX300 via the following commands:

    set interfaces ge-0/0/2 unit 0 family inet filter input 2nd-ISP

    set interfaces ge-0/0/2 unit 0 family inet address x.x.x.1/24

    set interfaces ge-0/0/3 unit 0 description "1st ISP"

    set interfaces ge-0/0/3 unit 0 family inet address y.y.y.2/30

    set interfaces ge-0/0/4 unit 0 description "2nd ISP"

    set interfaces ge-0/0/4 unit 0 family inet address z.z.z.2/24

    set firewall family inet filter 2nd-ISP

    set firewall family inet filter 2nd-ISP term 0 from source-address x.x.x.128/27

    set firewall family inet filter 2nd-ISP term 0 then routing-instance 2nd-router

    set firewall family inet filter 2nd-ISP term 1 then accept

    set routing-instances 2nd-router instance-type forwarding

    set routing-instances 2nd-router routing-options static route 0.0.0.0/0 next-hop z.z.z.1

    set routing-options interface-routes rib-group inet 2nd-router

    set routing-options static route 0.0.0.0/0 next-hop y.y.y.1

    set routing-options rib-groups 2nd-router import-rib [inet.0 2nd-router.inet.0]

    Now I wanted to configure the similar configuration on EX4600. Every commands is working fine except

    set routing-instances 2nd-router instance-type forwarding

    which gives a syntax error. and when I type

    set routing-instances 2nd-router instance-type ?

    No forwarding option is present. What would I need to change for this to work?

    The Junos feature explorer says this should be supported on the ex4600 if the version is 13.2X51-D25 or higher.  Are you above this version?
