ZXR10 5900E Series Configuration Guide (IPv4 Routing)
S4 and S1 establish an EBGP neighborhood, S1 and S2 establish an IBGP neighborhood,
S2 and S5 establish multi-hops EBGP neighborhood, see
static routes exist on S4.
S4 only advertises the network segment 192.16.0.0/16 by aggregation, and it uses a route
map to forbid BGP to advertise network segment 170.16.10.0/24. S2 and S5 establish an
EBGP multi-hop connection through S3. Ensure that the addresses used by two routers
(S2 and S5) to establish neighborhood can be pinged mutually.
