36. RIP operation all configurable RIP timers must be set at equal advertisement intervals on all router interfaces attached to common IPX network segments Note While you can set configurable RIP timers on any Bay Networks router interface do not use them on LAN interfaces because IPX servers do not allow configuration of update timers with internal routers As a result IPX servers will by default purge RIP entries after 180 seconds if they have not received any updates within this 180 second period 5 18 117369 A Rev A Customizing IPX For example in Figure 5 4 if router R1 is configured to issue periodic RIP advertisements every 240 seconds over interface 1 and router R2 is configured to issue advertisements per the IPX standard every 60 seconds over interface 2 then router R2 will purge RIP entries learned through Interface 2 every 180 seconds and reinstate them 60 seconds later when it receives a periodic RIP advertisement from router R1 More critically router R2 will issue triggered RIP updates through interface 3 propagating these unnecessary changes throughout the internetwork behind router R2 Setting the configurable RIP timers at 240 seconds on both interface 1 on router R1 and interface 2 on router R2 ensures proper RIP operation because RIP entries are not purged unless an update for a particular entry is not received within a 720 second interval 3 240 seconds Interface 1 Interface 3 RIP Update RIP
