📡 ENCOR 350-401 | Chapter 6
IP Routing Essentials
🔥 CCNA da aytilmagan KEY POINTS
━━━━━━━━━━━━━━━━━━
1️⃣ TERMINOLOGIYA FARQI
Path — ikki tarmoq orasidagi mavjud havolalar
Route — routing protokoli tanlagan yo'l (RIB da)
⚡️ CCNA da path = route deyiladi
ENCOR da bular FARQ QILADI
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
2️⃣ RIP TIMERLAR
🕐 Update → 30s (table yuborish)
🕐 Invalid → 180s (update kelmasa → invalid)
🕐 Holddown → 180s (yomon info bloklash)
🕐 Flush → 240s (table dan o'chirish)
⚡️ Holddown nima qiladi?
Route tushgandan keyin 180s davomida
"yaxshi" yangi ma'lumotni QABUL QILMAYDI
→ Routing loop oldini oladi
⚡️ RIP da Hello YO'Q
Qo'shni o'ligini 180s kutib bilib oladi
(OSPF = 40s, EIGRP = 15s)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
3️⃣ OSPF FLOODING QACHON TUGAYDI?
Down → Init → 2-Way → Exchange → FULL
⚡️ Router "tugadi" deb bilmaydi
U LSDB ni qo'shnisi bilan TAQQOSLAYDI
Full state = LSDB bir xil = sinxron
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
4️⃣ PATH SELECTION — 3 QADAM
1. Prefix Length /28 > /26 > /24
2. AD past AD → ustun
3. Metric past metric → ustun
📋 DEFAULT AD JADVALI
Connected → 0
Static → 1
eBGP → 20
EIGRP internal → 90 ✅
OSPF → 110 ✅
IS-IS → 115
RIPv2 → 120
EIGRP external → 170
iBGP → 200 ✅
⚡️ iBGP AD = 200
CCNA da o'tilmaydi
BGP iBGP path tanlasa → RIB ga AD=200
OSPF (110) uni preempt QILMAYDI
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
5️⃣ ECMP vs UNEQUAL LOAD BALANCING
ECMP → barcha IGP (RIP, EIGRP, OSPF, IS-IS)
• Metric bir xil → ikkala path RIB ga
• Traffic teng taqsimlanadi
Unequal-Cost → FAQAT EIGRP
• Default o'chiq — variance bilan yoqiladi
• Metric farqli → nisbatga qarab taqsimlaydi
⚡️ show ip route — ECMP ko'rinadi
⚡️ show ip route x.x.x.x — traffic share count
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
6️⃣ STATIC ROUTE — 3 TUR
Directly Attached
ip route net mask INTERFACE
→ Faqat P2P (Serial) da ishlating!
Recursive
ip route net mask NEXT-HOP-IP
→ Ethernet da xavfli — link tushsa
noto'g'ri interfeysga o'tib ketadi
Fully Specified ✅
ip route net mask INTERFACE NEXT-HOP-IP
→ Ethernet + static = HAR DOIM shu!
⚡️ Ethernet + Directly Attached = XATO
Har paket uchun ARP ishlaydi
→ CPU va xotira sarflanadi → tizim beqaror
⚡️ Ethernet + Recursive = XAVFLI
Link tushsa → RIP 180s kutadi
Static darhol noto'g'ri yo'lga o'tadi
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
7️⃣ FLOATING STATIC — BACKUP TEXNIKA
ip route 10.0.0.0 255.0.0.0 10.1.1.2 10
ip route 10.0.0.0 255.0.0.0 Serial1/0 210
AD=10 → asosiy (RIB da ko'rinadi)
AD=210 → backup (asosiy tushsa faollashadi)
⚡️ AD o'zgartirish routing loop ga
olib kelishi mumkin — ehtiyot bo'ling!
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
8️⃣ NULL0 — LOOP OLDINI OLISH
ip route 172.16.0.0 255.255.240.0 Null0
Aniq route (longer match) → yo'naltiriladi ✅
Aniq route yo'q → Null0 DROP ✅ (loop yo'q)
⚡️ Summary route + Null0 = standart pattern
ISP lar va enterprise da keng ishlatiladi
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
9️⃣ VRF — KOMANDALAR TARTIBI
vrf definition MGMT
address-family ipv4
interface GigabitEthernet0/3
vrf forwarding MGMT
ip address 10.0.3.1 255.255.255.0
⚡️ vrf forwarding kiritilganda
IP manzil AVTOMATIK o'chadi — normal holat!
Keyin qayta yozing
⚡️ show ip route — VRF interfeyslar KO'RINMAYDI
show ip route vrf MGMT — ko'rinadi
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🔟 RIB vs FIB — ENG MUHIM FARQ
RIB (Routing Table)
• Control Plane
• RAM da saqlanadi
• Best path hisoblash
• show ip route
FIB / CEF (Forwarding Table)
• Data Plane
• TCAM — hardware darajasida
• Real paket yo'naltirish
• show ip cef
⚡️ SDN va Controller-based arxitekturada
Control Plane va Data Plane ajratish
ENCOR ning asosiy mavzularidan biri

EIGRP external → 170
iBGP → 200 ✅
⚡️ iBGP AD = 200
CCNA da o'tilmaydi
BGP iBGP path tanlasa → RIB ga AD=200
OSPF (110) uni preempt QILMAYDI
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
5️⃣ ECMP vs UNEQUAL LOAD BALANCING
ECMP → barcha IGP (RIP, EIGRP, OSPF, IS-IS)
• Metric bir xil → ikkala path RIB ga
• Traffic teng taqsimlanadi
Unequal-Cost → FAQAT EIGRP
• Default o'chiq — variance bilan yoqiladi
• Metric farqli → nisbatga qarab taqsimlaydi
⚡️ show ip route — ECMP ko'rinadi
⚡️ show ip route x.x.x.x — traffic share count
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
6️⃣ STATIC ROUTE — 3 TUR
Directly Attached
ip route net mask INTERFACE
→ Faqat P2P (Serial) da ishlating!
Recursive
ip route net mask NEXT-HOP-IP
→ Ethernet da xavfli — link tushsa
noto'g'ri interfeysga o'tib ketadi
Fully Specified ✅
ip route net mask INTERFACE NEXT-HOP-IP
→ Ethernet + static = HAR DOIM shu!
⚡️ Ethernet + Directly Attached = XATO
Har paket uchun ARP ishlaydi
→ CPU va xotira sarflanadi → tizim beqaror
⚡️ Ethernet + Recursive = XAVFLI
Link tushsa → RIP 180s kutadi
Static darhol noto'g'ri yo'lga o'tadi
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
7️⃣ FLOATING STATIC — BACKUP TEXNIKA
ip route 10.0.0.0 255.0.0.0 10.1.1.2 10
ip route 10.0.0.0 255.0.0.0 Serial1/0 210
AD=10 → asosiy (RIB da ko'rinadi)
AD=210 → backup (asosiy tushsa faollashadi)
⚡️ AD o'zgartirish routing loop ga
olib kelishi mumkin — ehtiyot bo'ling!
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
8️⃣ NULL0 — LOOP OLDINI OLISH
ip route 172.16.0.0 255.255.240.0 Null0
Aniq route (longer match) → yo'naltiriladi ✅
Aniq route yo'q → Null0 DROP ✅ (loop yo'q)
⚡️ Summary route + Null0 = standart pattern
ISP lar va enterprise da keng ishlatiladi
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
9️⃣ VRF — KOMANDALAR TARTIBI
vrf definition MGMT
address-family ipv4
interface GigabitEthernet0/3
vrf forwarding MGMT
ip address 10.0.3.1 255.255.255.0
⚡️ vrf forwarding kiritilganda
IP manzil AVTOMATIK o'chadi — normal holat!
Keyin qayta yozing
⚡️ show ip route — VRF interfeyslar KO'RINMAYDI
show ip route vrf MGMT — ko'rinadi
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🔟 RIB vs FIB — ENG MUHIM FARQ
RIB (Routing Table)
• Control Plane
• RAM da saqlanadi
• Best path hisoblash
• show ip route
FIB / CEF (Forwarding Table)
• Data Plane
• TCAM — hardware darajasida
• Real paket yo'naltirish
• show ip cef
⚡️ SDN va Controller-based arxitekturada
Control Plane va Data Plane ajratish
