I believe Bob was saying he had done exactly that Doug. My experience is that changing the default gateway can be a pain and the only way to be absolutely sure when this sort of stuff happens is to remove the interface via smitty devices then add it back again and configure it. Sorry.
The other possibility is that you have two or more physical interfaces (en0 and en1 say) and someone has configured them as a link aggregation or etherchannel to create a pseudo-device (en2), but that in reconfiguring the gateway, the reconfiguration has been applied to one of the physical devices en0 or en1, instead of to the link aggregated device...

If you manually add/delete routes WITHOUT using smit then the "come back" when you reboot do the following: smitty tcpip select ==> Minimum Configuration & Startup select your network card and then change Default Gateway Address (dotted decimal or symbolic name) [172.16.0.255] to whatever your gateway is, this will update the ODM and next time you reboot will be the gateway thats set dougc Bob Witney wrote: > Ok I know that this is a tad of topic but I am hoping that those nice > IBM chaps are monitoring > > > > We are on a Pseries running AIX 5.3 and Universe 10 > > > > We have changed out default gateway, > > > > I know, leave things alone I say, if its not broken don't fix it, but > you know what there network techies are like, fiddle, fiddle, fiddle > > > > Anyway: > > > > we user smit assist - Configure Network Communications' - TCP/IP > Startup - pick our interface > > > > Drop down to default gateway and change the ipaddress > > > > Works fine > > > > Until we re-boot at which point it reverts to the default gateway we had > before the change > > > > It may be we should run ifconfig or something to "lock" our change in > but I can't see it anywhere in the books > > > > Any suggestions would be great > > > > Bob Witney > > IT Senior > > Explore Worldwide > > Nelson House > > 55 Victoria Road > > Farnborough > > Hants > > GU14 7PA > > > > > Confidentiality Notice: This e-mail and any attachments are intended solely > for the addressee and may contain confidential or privileged information. > If you are not the named addressee, or the person responsible for delivering > the message to the named addressee, please notify the sender as soon as > possible and delete the material from your computer.
