Hi!
I'm testing a config in my lab for an eBGP peering on
2 4700 routers with a remote router but there is a
2600 (64MB RAM) in between.
|4700| --
|-- |2600| -- |remote router (diff AS)|
|4700| --
The 2600 does nothing but provide a serial port to my
peer and is connected to the 4700s via fastethernet.
What is the best way to implement the setup?
Do I have to use ebgp multihop like the one below?
one of two 4700:
Interface Fastethernet0/0
ip address 10.0.0.1 255.255.255.0
router bgp 64888
neighbor 10.8.8.1 remote-as 64777
neighbor 10.8.8.1 send-community
neighbor 10.8.8.1 route-map setAttrib in
neighbor 10.8.8.1 ebgp-multihop 2
ip route 10.8.8.0 255.255.255.252 10.0.0.2
remote router:
Interface Serial0/0
ip address 10.8.8.1 255.255.255.0
router bgp 64777
neighbor 10.0.0.1 remote-as 64888
neighbor 10.0.0.1 send-community
neighbor 10.0.0.1 route-map setAttrib in
neighbor 10.0.0.1 ebgp-multihop 2
ip route 10.0.0.0 255.255.255.252 10.8.8.2
How do I configure the 2600 in between?
The BGP state is established but a routing loop
occurs on the 2600 when I do traceroutes with test
"customers" connected to the remote router and 4700
simply because it doesn't know where to properly route
the packets. It only knows the two directly connected
networks on it.
As much as possible, I don't intend to run an IGP nor
iBGP on the 2600 due to memory constraints if deployed
in actual scenario with full Internet routing table.
If the above config won't work, please give
suggestions examples and links. Would private AS on
the 2600 work or simply run iBGP on it with the 4700s?
If only I can buy a new 7206 with many serial ports
tomorrow...that's another story... :(
TIA
