Hi Experts,
Recently I have purchased a Cisco 2921/K9 ISR router with UCS Server Module which I will use to install CUCM & CUC.
However, I have a bit confused on the interface connection.
Below is the config guide provided by my senior. Let's called it example 1
bridge irb
!
int gi0/1
no ip address
duplex auto
speed auto
bridge-group 1
no shut
!
int ucse1/0
ip unnumbered BVI1
service-module heartbeat-reset disable
imc ip address 192.168.20.3 255.255.255.0 default-gateway 192.168.20.2
imc access-port lom-shared
bridge-group 1
no shut
!
interface BVI1
description Virtual Interface connecting to the Switch
ip address 192.168.20.2 255.255.255.0
ip pim sparse-dense-mode
ip igmp version 3
!
bridge 1 route ip
Can I assume that by configure the ISR as above, I will only need a cable connect from int gi0/1 to the switch ?
Below is another example I got from the internet and let's called it example 2
interface GigabitEthernet0/1
ip address 10.0.234.58 255.255.255.192
!
interface ucse1/0
ip unnumbered GigabitEthernet0/0
imc ip address 10.0.234.59 255.255.255.192 default-gateway 10.0.234.58
imc access-port shared-lom console
!
ip route 10.0.234.59 255.255.255.255 ucse2/0 [CIMC]
ip route 10.0.234.60 255.255.255.255 ucse2/0 [ESXi]
So if I am using the configuration in example 2, I will need 2 cable (int gi0/1 to switch & int ucse1/0 to switch).
I only have 2 port on from the switch hence in the example above i am using lom-shared for the cimc.
Can anyone advise which is the better way to configure the ISR router ?
Also from the switch side, is it just configure all port as access port for the voice vlan and assign a SVI for it ? have a little confusion over this part.
Thank you very much in advance.
