Verifying the configuration
# Verify that Router A can successfully ping Router B and Router C. (Details not shown.)
# Verify that Router B and Router C cannot ping each other. (Details not shown.)
MP for DDR configuration example
Network requirements
As shown in
are connected across ISDN.
Configure Router A to call Router B by using bundle DDR, and configure Router B to call Router A by
using traditional DDR. In addition, implement traffic distribution for the two interfaces on Router A by
setting traffic thresholds.
