dear all,
i have encountered a BGP scenario which baffles me, and i need some advice on
this...
topology is like this:
R1 (dlci=102)-------(dlci=201) R2 (dlci=203)--------(dlci=302) R3
s0 s0
s0
configured on R1:
int s0
encapsulation frame-relay
no frame-relay inverse-arp
frame-relay map ip 100.100.123.1 102
frame-relay map ip 100.100.123.2 102 broadcast
frame-relay map ip 100.100.123.3 102 broadcast
ip address 100.100.123.1 255.255.255.0
ip ospf priority 0
router ospf 1
router-id 100.100.1.1
network 100.100.1.0 0.0.0.255 area 0
network 100.100.123.0 0.0.0.255 area 0
on R2:
int s0
encapsulation frame-relay
no frame-relay inverse-arp
frame-relay map ip 100.100.123.1 201 broadcast
frame-relay map ip 100.100.123.2 201
frame-relay map ip 100.100.123.3 203 broadcast
ip address 100.100.123.2 255.255.255.0
ip ospf priority 100
router ospf 1
router-id 100.100.2.2
network 100.100.2.0 0.0.0.255 area 0
network 100.100.123.0 0.0.0.255 area 0
neighbor 100.100.123.1
neighbor 100.100.123.3
lastly, on R3:
int s0
encapsulation frame-relay
no frame-relay inverse-arp
frame-relay map ip 100.100.123.1 302 broadcast
frame-relay map ip 100.100.123.2 302 broadcast
frame-relay map ip 100.100.123.3 302
ip address 100.100.123.3 255.255.255.0
ip ospf priority 0
router ospf 1
router-id 100.100.3.3
network 100.100.3.0 0.0.0.255 area 0
network 100.100.123.0 0.0.0.255 area 0
if i am to configure BGP on R1, R2 and R3 using AS100 and have to use R3 as
route-reflector, may i use the following configuration on R3?
router bgp 100
bgp router-id 100.100.3.3
bgp cluster-id 100
neighbor clients peer-group
neighbor clients remote-as 100
neighbor clients update-source loopback 0
neighbor clients route-reflector-clients
neighbor 100.100.1.1 peer-group clients
neighbor 100.100.2.2 peer-group clients
the reason i am asking this question is, on my Cisco IOS IP Configuration
Guide 12.2 hardcopy, it has a line which i quote: "NOTE: IF CLIENT-TO-CLIENT
REFLECTION IS ENABLED, THE CLIENTS OF A ROUTE REFLECTOR CANNOT BE MEMBERS OF A
PEER GROUP." (IPC-304) but this line has been removed on the online documents
and therefore, i cannot see this line appearing on either 12.1 nor 12.2 of the
online docCD.
so, is it safe to assume that i can use peer-groups with route-reflectors, as
in my case?
Emmett
