I think it is really the shame that in situation of multiple gateway, illumos DHCp as a client takes both and then sometimes uses one gateway sometimes another.

It is usually first gateway is meant to be the default gateway and the other to be used only if the first one is not able to forward packets

it really depends on your network whether you want failover or ECMP (equal-cost multipathing) or something more complicated. The illumos kernel forwarding table does something ECMP-ish when there are multiple routes and I don't believe there's any notion of a standby route in the kernel forwarding table.

nice:)

also nice: power was just restored to my place :)

gz:)

been out since thursday night

ouch. winds?

yeah

yea, happens here a lot too

had some really bad storms with some extremely powerful winds that basically went right through the city

took down several of the big transmission lines

lots and lots and lots of downed trees

almost 200 km/h winds

if my conversion is correct (120 mph)

53m/s

almost 1 million people lost power

jbk: Houston area?

rather bad, yep. well, fun fact, 50-55 m/s is terminal speed for human flying on belly:)

sommerfeld: yes

i'm just south of i-10 in the 'inner loop'

the area just north of i-10 looks like it got hit the hardest

that and a far NW suburb (cypress)

when the derecho hit DC years ago, we just drove until power existed again and went "camping"

(though for future reference, if you're going to drive 3 hours from DC _north_ is the direction to do that, any other direction gets... local)

heard some banjos? :)

though north (unless you went the whole 5+ hours to Dallas) was probably the wrong move since just a few weeks before, the area north of houston had some pretty severe flooding and probably isn't entirely recovered yet from that

for here

so Austin or San Antonio

but i have an elderly cat, who doesn't like going in any vehicles, so i figured i'd try to avoid stressing her out if i could avoid going elsewhere

though with the temps this afternoon, i was to the point of leaving had power not come back on

I'm glad it did

nikolam: If you can find some description (say, in an RFC) of the intended behaviour when DHCP provides two default routers we can certainly look at fixing the behaviour somehow

oh, they're gone

Anyway the idea of a "warm spare" second gateway being provided through DHCP is something I've never heard of, and seems a bit silly. How do you know when the "primary" is down, without a routing or heartbeating protocol anyway

jclulow: would have to be a heuristic like failure to respond to arp

Yeah that seems pretty fraught

This is why people either do VRRP style network-side HA, or they just do BGP/BFD/whatever

Mind you if someone wants to add the ability to illumos to do neighbour liveness via ARP/NDP for next hops, knock yourselves out haha

having an option in /etc/default/dhcpagent to limit the number of default routes we're willing to install would deliver 90% of what was needed for 10% of the effort...

Yes indeed
