[SunHELP] SOLVED - multiple ip addresses with link-based ipmp

[Eddie Watkins]

I forgot to specify the netmask.  Adding it again with a netmask worked fine.

Subject: [SunHELP] multiple ip addresses with link-based ipmp

I have inherited responsabilty for a Sun V245 with Solaris 10.  This server
has link-based ipmp with a single ip address.  There is now a requirement to
assign multiple ip addresses to this machine.  There is an active (bge0) and
standby (bge1) nics on the server.

I tried running ifconfig bge0 addif xx.xx.xx.59 up which seemed to work, but
telnet access then took about 2 mins to connect and any browser based access
to the original ip address would just time out.

I have amended /etc/hosts to include the ip addresses that I want to use.
output of ifconig -a before adding the interface is

lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232
index 1
        inet 127.0.0.1 netmask ff000000
bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet xx.xx.xx.58 netmask ffffffc0 broadcast xx.xx.xx.63
        groupname grp1
        ether 0:14:4f:a2:3e:ce
bge0:1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 0.0.0.0 netmask ff000000 broadcast 0.255.255.255
bge1:
flags=69000842<BROADCAST,RUNNING,MULTICAST,IPv4,NOFAILOVER,STANDBY,INACTIVE>
mtu 0 index 3
        inet 0.0.0.0 netmask 0
        groupname grp1
        ether 0:14:4f:a2:3e:cf

output after ifconfig command is

lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232
index 1
        inet 127.0.0.1 netmask ff000000
bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet xx.xx.xx.58 netmask ffffffc0 broadcast xx.xx.xx.63
        groupname grp1
        ether 0:14:4f:a2:3e:ce
bge0:1: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 0.0.0.0 netmask ff000000 broadcast 0.255.255.255
bge0:2: flags=1000842<BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet xx.xx.xx.59 netmask ff000000 broadcast 10.255.255.255
bge1:
flags=69000842<BROADCAST,RUNNING,MULTICAST,IPv4,NOFAILOVER,STANDBY,INACTIVE>
mtu 0 index 3
        inet 0.0.0.0 netmask 0
        groupname grp1
        ether 0:14:4f:a2:3e:cf

/etc/hostname.bge0 looks like
# cat hostname.bge0
thishost/26 broadcast + group grp1 up

and hostname.bge1 looks like

# cat hostname.bge1
group grp1 standby up

Am I doing it the right way, or is there another method that I should use?



Thanks

Eddie
