after a reboot I no longer have the road to ipsec VTI

  • F

    HI,

    after a reboot I no longer have the road to ipsec VTI, as a workaround I have to revalidate the gateway System -> Routing -> Gateways -> Edit VTI Gateway -> Save -> Apply .

    netstat -rn | egrep '(ipsec2|10.8.222)'
10.8.222.1         link#12            UH     ipsec200
10.8.222.2         link#12            UHS         lo0
fe80::%ipsec2000/64               link#12                       U      ipsec200
fe80::20c:29ff:fe2c:fe96%ipsec2000 link#12                      UHS         lo0
    • Apply workaround

    Where do you have the route set for 10.60.0.0/16? Is it a static route, handled by a routing protocol (OSPF or BGP) or what?

    Hi Jimp,

    Yes add static route

    	<staticroutes>
		<route>
			<network>10.60.0.0/16</network>
			<gateway>IPSECVTI_VTIV4</gateway>
			<descr><![CDATA[Route VTI]]></descr>

    Hmm, I just checked the setups I have here with VTI and static routes and they all apply at boot time.

    Did you make manual changes to the VTI gateway? Try removing the VTI gateway settings (click the trash can) -- that will not actually delete the gateway since it is dynamic, only its custom settings. Then reboot and see if it works.
