Are yo referring to the Cisco 2500 Series Routers?
Do you have them in a production network environment or in your personal lab to learn/play?
If you have them in a network production environment, I guess it is time to look for a replacement like the ISR 4000 series.
If you have them in your lab, it may be easier to practice IPv6 in a virtualized environment like VIRL.
Cheers.

Some platforms part of the Cisco Nexus 3000 and Cisco Nexus 9000 family of Switches support NAT.
Cisco Nexus 9000 Series NX-OS Interfaces Configuration Guide, Release 7.x Chapter: Configuring Static and Dynamic NAT Translation
Cisco Nexus 3000 Series NX-OS Interfaces Configuration Guide, Release 7.x Chapter: Configuring Static and Dynamic NAT Translation
As mentioned already, Catalyst 3850 does not support NAT.
PS: Make sure to go thru the Guidelines and Limitations section before configuring NAT on the Cisco Nexus 3000 or 9000.
Cheers.

Hi @blinchik.
If you are connecting your Routers back to back over GigabitEthernet0/0, the config should look like:
Router 1
interface GigabitEthernet0/0
ip address 192.168.5.1 255.255.255.0
no shutdown
Router 2
interface GigabitEthernet0/0
ip address 192.168.5.2 255.255.255.0
no shutdown
Their Layer 3 interfaces need to be in the same subnet to communicate.
Hope this helps.
Cheers.

It looks to me cosmetic in the sense of how the CEF output presents the information when you have more than one path available.
What IOS version are you running on your device?

Hi @gowdakssujan,
The reception of EIGRP Hello packets (Multicast pkts destined to 224.0.0.10) does not generate any kind of ACK packet as a response.
Cheers.

HI @Muthukumar P,
You need an IOS image that includes crypto/SSH code, which are those with k9 in the name.
- You have cat4500e-entservices-mz.152-2.E8.bin
- You need cat4500e-entservicesk9-mz.152-2.E8.bin
For your platform, it can be found here:
Software Download - Catalyst 4500 Supervisor Engine 6-E
Hope this helps.
Cheers.

Hi @Isaac ,
When enabling Multicast PIM related commands, I do not expect disruption of Unicast traffic.
Cheers.

Perhaps you have another HSRP or VRRP instance already running on a different interface.
There is a limitation on this platform documented here:
"No more than two variations of the both VRRP and HSRP protocols are supported when configuring VRRPv3. For example, if both VRRP for IPv4 and VRRP for IPv6 are configured, HSRP cannot be configured."

If port 3 accepts the command no switchport (to make it Layer 3), you can then configure the IP address directly in the port and that is the IP address that will communicate with your Switch since to this interface you are connecting that Switch.
If 'no switchport' is rejected, the port is Layer 2 only and by default it belongs to vlan 1. You can modify the vlan association by running switchport access vlan X in the port configuration where X is any vlan number within the accepted range. In this case, interface vlan X is where you need to configure the IP address.

Those LAN ports on the Router are Layer 2 (L2) ports.
You can configure an interface Vlan for the vlan configured on the L2 port connecting to the Switch.
Btw, nice lab!

That's correct.
Still, I'd suggest you to enable ip routing. The main reason is that the reception of ICMP redirects (if any) can create entries in your routing table in this mode.

Hi @mhiyoshi,
I would expect the order of operations to be the same on both.
