[VLAN] Overlapping IPs on different VLANs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



 

 

I have two VLANs configured on a box as shown below with overlapping IPs
on different VLANs.

If C (IP2 on the right) sends a packet to IP1 (A) on VLAN 100, the
packet is dropped as a martian since IP2 is a local address on A (even
though its on a different VLAN).

 

Is there a way (some setting or a patch) to fix this? (There's an
rp_filter setting but that's not for local addresses)

 

 

  ---------------------

  |                    |   VLAN 100        ---------

  |     IP1 (eth0.100) |----------------- |IP2      |

  |                    |                  |       B |

  | A                  |                   ---------

  |                    |   VLAN 101        ---------

  |     IP2 (eth0.101) |----------------- | IP1     |

  |                    |                  |       C |

  ---------------------                    ---------

 

 

TIA
