I have a 7206 router I am replacing with a newer 7206 that connects all remote branches.
My existing 7206 is using BGP to connect remote sites and distributing BGP into OSPF.
I have the second router up and running connected to the network by a single ethernet interface. There are no issues at the moment.
I want to have both routers up while I swap out everything, swapping an interface at a time while I make sure the new router is going to be ok.
The existing router has all connections intact including serial connections to DR and all remote branches.
Existing router has an interface
10.1.70.1 on the LAN
New router has an interface
10.1.71.1 on the LAN
OSPF is getting routes from the two core switches on the new 7206.
Is there any potential problem (from the standpoint of conflicting BGP processes by using the same AS number) if I just apply the config on the existing 7206 to the new 7206 while both are up?
The BGP config is as follows:
router bgp 65001
network 10.1.0.0 mask 255.255.0.0
network 10.1.70.0 mask 255.255.255.0
network 10.5.0.0 mask 255.255.0.0
network 172.16.254.1 mask 255.255.255.255
redistribute static route-map STATICtoBGP
redistribute ospf 1 match internal external 2
