So I understand that I need one vlan pool for VMM domain, which include a static entry range; and another vlan pool for L3 domain. The two polls should have same static vlan used for l3out. I will try it soon. but why I need to create the EPG you write in your reply?

My question is:
The ACI integrates with vCenter.
I want to use a vm as a external router(eve-ng）.
I don't know if I can use same ACI interface which connect to VMware Hypervisor for L3 out interface config?
If it work, how to implement it ?
Thank a lot!

Yes, I have noticed the 2900 router, but ' Cisco announces the end-of-sale and end-of-life dates for the Cisco 2900 Series Integrated Services Routers. The last day to order the affected product(s) is December 9, 2017. '
So is there any other option??

My customer have some DLSW config on a Cisco 2811 router, but now Cisco 2811 router is EOS and EOL，it means the product can't get any support service now.
My customer don't want to change original DLSW config in futrure new device.
So I try to find a new Cisco device which can support DLSW and replace the old Cisco 2811.
But I didn't find a suitable such device.
Who can give me any suggestion about the question?
Thank you!

To make it more clear:
In my lab,
dns server: two router configed as dns server, r2 (w/ ip 192.168.100.2) and r3 (w/ ip 192.168.100.3, 192.168.34.3) dns client: one router confied as dns client, r4(w/ ip 192.168.34.4)
I hope r3 is coniged as dns server and I don't want to config r2 as r3's dns server by using command 'ip name-server 192.168.100.2'. But I till hope r3 can forward 'baoshan.com' dns query to r2 by using command 'ip host baoshan.com ns ns2.baoshan.com'. My question is that r3 didn't forward the dns query to r2. here is more config: r2: r2#sh run | include dns|host int e0/0 ip add 192.168.100.2 ! hostname r2 ip host test.baoshan.com 44.44.44.44 ip host ns2.baoshan.com 192.168.100.2 ip host baoshan.com ns ns2.baoshan.com ip dns server ip dns primary baoshan.com soa ns2.baoshan.com mx2.baoshan.com ! router ospf 1 network 0.0.0.0 255.255.255.255 area 0 ! R3: ! ip host ns2.baoshan.com 192.168.100.2 ip dns server ip host baoshan.com ns ns2.baoshan.com (I hope r3 should forward 'baoshan' dns query to ns2 which is r2 dns server) (followed command although I think is not needed, but I have tried these command and failed) ip dns primary baoshan.com soa ns2.baoshan.com mx2.baoshan.com ! int e0/0 ip add 192.168.100.3 255.255.255.0 ! int e0/1 ip add 192.168.34.3 255.255.255.0 ! router ospf 1 network 0.0.0.0 255.255.255.255 area 0 ! router r4: ! ip domain-lookup (default) ip name-server 192.168.34.3 ! int e0/0 ip add 192.168.34.4 255.255.255.0 ! router ospf 1 network 0.0.0.0 255.255.255.255 area 0 !

Here is the command explaination:
ip host domain-name ns server-name
Example: Device(config)# ip host example.com ns ns1.example.com (Optional) Configures the device to create an name server (NS) resource record to be returned when the DNS server is queried for the associated domain. This configuration is needed only if the zone for which the system is authoritative will also be served by other name servers

No, it didn't work.
after I change config as what you say,
r3 config:
ip host baoshan.com ns ns2.baoshan.com ip host ns2.baoshan.com 192.168.100.2
ip dns server ip dns primary baoshan.com soa ns2.baoshan.com mb2.baoshan.com

Here is my config:
r3:
(dns server)
ip dns server
ip domain lookup
ip host baoshan.com ns ns2 ip host ns2 192.168.100.2
!
r4:
(dns client)
ip domain lookup
ip name-server 192.168.34.3 ( which is r3 ip address)
!
r4: ping test.baoshan.com
r3 didn't forward dns query to ns2 based on the "ip dns baoshan.com ns ns2" config, r3 at last sent out broadcast dns query. I want to know why and how to make dns ns config work?
Followed is r3's debug domain output:

this time we do otv test. we found when internal interface fail(eg.interface down), it neet 10-15s for AED switch to another AED. 10-15s is too long for data center application. so my question is: 10-15s is normal convergence time when internal interface down？

1/ here we use nexus 5k, nx-os, so may be command is little different. 2/ nx-os snmpv3 config may be modified as： snmp-server user admin network-admin auth md5 xxxx priv zzzzz snmp-server host 10.88.32.200 traps version 3 public udp-port 1163 ( it seems only traps version need be modified from 2c to 3) 3/ by the way, it seems original snmp config is added by dcnm during install dcnm software. 4/ verify snmpv3 work is a good method,we will try it first. thanks.
