Rohit Yadav reassigned CLOUDSTACK-8945:
---------------------------------------
Assignee: Rohit Yadav
> rp_filter=1 not set on VPC private gateway initially, but is set after
> restart of VPC router
> --------------------------------------------------------------------------------------------
>
> Key: CLOUDSTACK-8945
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8945
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Virtual Router
> Affects Versions: 4.4.4
> Reporter: Anton Opgenoort
> Assignee: Rohit Yadav
>
> (on ACS4.4.4 with XenServer as hypervisor)
> Steps to reproduce:
> -create VPC router
> -Create private gateway on VPC router
> -now log on to the rVM via the hypervisor's link-local address
> root@r-46771-VM:~# sysctl net.ipv4.conf.eth2.rp_filter
> net.ipv4.conf.eth2.rp_filter = 0
> Restart the rVM via CloudStack (NOT restart VPC but restart the underlying
> router via CloudStack)
> -log on again:
> root@r-46771-VM:~# sysctl net.ipv4.conf.eth2.rp_filter
> net.ipv4.conf.eth2.rp_filter = 1
> The issue thus is that on initial creation it is not set, where it should be
> set immediately
> Note: when adding a regular network tier to the VPC config, that new
> interface IS configured with rp_filter=1. So it is limited to the private
> gateway NIC.
