السلام عليكم
أرجو مساعدتي في التالي
The reach people's bank has five branches
A central one that we studied in part one is located in Hamraa Street, other branches are located in Mazzeh, Dummar, Muhajreen, and Kassaa
All these branches are connected to each other via Leased lines using OSPF as routing protocol.
1- The central branch router receives the following LSAs:
Link Weight
Mazzeh→ Hamraa 2
Mazzeh→ Kassaa 2
Link Weight
Dummar→ Hamraa 1
Dummar→ Kassaa 3
Link Weight
Muhajreen→ Hamraa 4
Link Weight
Kassaa→ Mazzeh 2
Kassaa→ Dummar 3
Give the forwarding table for Hamraa Router.
2- Now as many new banks operate here in Syria our bank gets many competitors so the administration decided to open new branch in Damascus Airport,
The central branch has received these LSAs:
Link Weight
Dummar→ Hamraa 1
Dummar→ Kassaa 3
Dummar→ Airport 1
Link Weight
Muhajreen→ Hamraa 4
Muhajreen→ Airport 1
Link Weight
Kassaa→ Mazzeh 2
Kassaa→ Dummar 3
Kassaa→ Airport 3
Link Weight
Airport→ Dummar 1
Airport→ Muhajreen 1
Airport→ Kassaa 3
Give the new forwarding table for Hamraa Router.
3-Assume that the link between Hamraa Router and Dummar Router fails and must be withdrawn. Assume further that the link between Hamraa Router and Muhajreen Router becomes less congested, and so both Hamraa and Muhajreen Routers recalculate the cost of the Hamraa ↔ Muhajreen link to be 1.
(i) Give the updated LSAs that Hamraa, Dummar, and Muhajreen Routers send.
(ii) Give the updated forwarding table for Dummar Router.
(iii) Give the updated forwarding table for Muhajreen Router.
